Grade Date:Speed law -- Time, Speed and Distance Calculator
Speed and Distance CalculatorExample 1
A car travels 300km in 6 hours. What is the speed of the car?
Answer:Speed = distance timeSpeed = 300km 6 hoursSpeed = 50km/hr
Example 2If your school bus took half an hour to travel 10 kilometres to school, its average speed would
be:
Answer:
v = d/tv = 10 = 20 km/h
0.5 More practice1. How far can a plane travel if it flies 800km/hr for 9 hours?Answer:
d= v t
800km/hr 9hrs = 7200km
