Speed, distance and time are all linked, and this skill is about using that link to solve everyday problems, from how fast someone is travelling to how long a journey takes, as well as rates like filling a tank, sharing out work and getting a job done in time.
In this Speed, Distance, Time and Rates pack, your child will practise:
- Working out speed, distance or time when the other two are known
- Converting between units such as km/h, mph, metres per second and minutes and hours
- Comparing two journeys to find the difference in speed or how many times faster one is
- Working with speed and distance ratios between two travellers
- Solving journeys with stops, breaks or changes of speed part way through
- Reading and interpreting distance-time graphs, including resting and extrapolating a steady speed
- Using bus and train timetables to plan journeys, find missing times and work out service intervals
- Solving relative-motion problems where objects move towards, away from or catch up with each other
- Calculating filling and emptying rates for tanks and pools, including a simultaneous leak
- Working out how long a job takes with different numbers of workers using inverse proportion
- Solving everyday rate problems such as production output, pay, bounces and repeating cycles
