Question

It took a car driver 30min to travel a distance of 50km. What is the average speed?

Answer 1

How far would it go if you drove 1 hour?
So what's the average in km/hr

Answer 2

Average velocity=Total distance travelled÷Total time taken
Total distance=50Km, Time taken=0.5hrs(½ an hour)
So,50÷0.5=100km/h
