Question

A car moves at a speed of 20 km/ hr for 15 min. And then at a speed of 60 km/hr for next 15 min. , Calculate the total distance covered by the car

Answer 1

Answer:

The total distance covered by the car = 20 km

Explanation:

As we know that speed

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

thus the distance covered by the body in the first 15 minutes (= 1/4 hour) with velocity 20 km/hr is

distance = speed × time

= 20 × 1/4 = 5km

In the next fifteen minutes with velocity 60 km/hr

= 60 × 1/4 = 15 km

HENCE total distance = 5 + 15 = 20km
