Question

how long will it take a car traveling of a constant speed of 45m/s to cover the distance of a 2.5km?

Answer 1

speed of the car = 45 m/s

distance traveled by the car = 2.5 km

here we know that

1 km = 1000 m

so we will have

distance = 2500 m

now in order to find out the time of motion we will have

$time = \frac{distance}{speed}$

$t = \frac{2500}{45}$

$t = 55.55 s$

so it will take 55.55 seconds
