Question

How long does it take a car traveling at an average speed of 20 m/s to complete a 4 km journey?

Answer 1

200 seconds are required

*Explanation:

speed:20 m/s

distance:4km

time:?

so we need to find the amount of time in this word problem but first all the units should be the same so convert km to m

To do this (multiply by 1000)

4 km × 1000 = 4000m

now write the formula for finding time which is

`time = (distance)/(speed)`

`time = (4000)/(20)`

time= 200 seconds
