Journey Times maths mission
A junior real-world challenge using journey times to practise time without feeling like a worksheet.
Quick answer
Journey times maths mission helps you work out how long it takes to travel from one place to another, using speed, distance, and time – just like real-life journeys!Learning outcome
By the end of this page, you will be able to calculate how long a journey takes using the formula: Time = Distance ÷ Speed. Success signs:- You can tell how long it takes to walk from your house to school
- You can work out how long a car trip will take
- You can use a timetable to plan a journey
- You can estimate journey times in your head
Why this matters
Understanding journey times helps you plan your day, know when to leave for the bus, and make sure you arrive on time. It’s useful for trips, school, sports, holidays, and even when you're playing games where you need to move quickly or plan your route. In real life, journey times help parents decide when to leave for the airport, or how long a train ride will take. In games like Minecraft or Roblox, you might need to plan how long it takes to build something or travel across a map. Even in sports like football, knowing how long it takes to run from one side to the other can help you score goals.How it works
To work out journey times, we use a simple formula: Time = Distance ÷ Speed Let’s break it down step by step: 1. First, find the distance – how far you are going. 2. Then, find the speed – how fast you are going. 3. Finally, divide the distance by the speed to get the time. For example, if you walk 6 km at a speed of 2 km per hour, your journey takes 6 ÷ 2 = 3 hours. This works the same way for cars, bikes, or even flying. The key is knowing the distance and speed.Examples you can see
Let’s imagine a journey from your house to the park. Example 1: Walking to the park - Distance: 3 km - Speed: 1 km per hour - Time = 3 ÷ 1 = 3 hours That’s a long walk! But maybe you’re walking slowly or taking a break. Example 2: Cycling to the park - Distance: 6 km - Speed: 3 km per hour - Time = 6 ÷ 3 = 2 hours Cycling is faster than walking, so it takes less time. Example 3: Driving to the park - Distance: 12 km - Speed: 4 km per hour - Time = 12 ÷ 4 = 3 hours Driving is faster than cycling, so it takes less time. You can also use this to plan a trip to a friend’s house: Example 4: Driving to a friend’s house - Distance: 15 km - Speed: 5 km per hour - Time = 15 ÷ 5 = 3 hours That’s a long drive, so maybe you’d take a bus or walk instead.Try it as a mini adventure
Let’s go on a journey to find out how long it takes to get to different places. Adventure: Journey Times Maths Mission You are a travel explorer! You need to find out how long it takes to travel from your home to different places. 1st time: You walk to the local shop. It is 2 km away. You walk at 1 km per hour. How long does it take? 2nd time: You ride your bike to the library. It is 4 km away. You ride at 2 km per hour. How long does it take? 3rd time: You take the bus to the playground. It is 8 km away. The bus travels at 4 km per hour. How long does it take? 4th time: You fly to a nearby city. It is 12 km away. You fly at 6 km per hour. How long does it take? 5th time: You swim to the beach. It is 10 km away. You swim at 5 km per hour. How long does it take? Can you solve each journey? Answers: 1st time: 2 ÷ 1 = 2 hours 2nd time: 4 ÷ 2 = 2 hours 3rd time: 8 ÷ 4 = 2 hours 4th time: 12 ÷ 6 = 2 hours 5th time: 10 ÷ 5 = 2 hours All journeys take 2 hours! That’s a fun way to explore how speed and distance change time.Common mistakes
- Mistake: Forgetting to use the same units for distance and speed. Why it happens: If distance is in km and speed is in m/h, it can confuse the calculation. Fix: Always check that distance and speed are in the same units (e.g., km and km/h).
- Mistake: Adding instead of dividing. Why it happens: Sometimes children mix up the formula and add numbers. Fix: Remember: Time = Distance ÷ Speed. Always divide, not add.
- Mistake: Not checking if the answer makes sense. Why it happens: If you get a really big or small answer, it might be wrong. Fix: Ask yourself: “Does this make sense?” If you walk 2 km at 1 km/h, it should take 2 hours – that sounds right!
Parent and carer guide
As a parent or carer, you can help your child understand journey times in these ways: 1. Use real-life situations: Talk about your own journeys – “It takes 30 minutes to get to the shops by car.” 2. Use a map or timer: Draw a route and time how long it takes to walk or cycle it. 3. Play the journey game: Ask questions like, “If you ride your bike 10 km at 5 km/h, how long will it take?” 4. Use apps or games: Some apps let you plan journeys and see how long they take. 5. Be patient: It’s okay if your child makes mistakes – they’re learning! Don’t worry if your child doesn’t get it right away. Practice makes progress, and it’s a fun way to learn maths!Practice questions

FAQ
What is a journey time?
Journey time is how long it takes to travel from one place to another. It depends on the distance and how fast you go.
How do I work out journey time?
You use the formula: Time = Distance ÷ Speed. Just divide the distance by the speed.
Can I use this for any journey?
Yes! You can use it for walking, cycling, driving, flying, or even swimming. Just make sure the distance and speed are in the same units.
Why is it useful to know journey times?
Knowing journey times helps you plan your day, make sure you’re not late, and understand how far you can travel in a certain time.
What if the speed changes during a journey?
If the speed changes, you can still estimate the journey time. You can work out the average speed or break the journey into parts and add the times together.
