Question

A car moves with a velocity of 20 m/s to east and the other with velocity of 15 m/s to west. If they move from the same point, how far will each of them travel in 2 minutes? Calculate the distance between them after 2 minutes​

Answer 1

4.2 km

Step-by-step explanation:

CAR A(velocity =20m/s to East)

In 1s, it covers 20m.

In 120s(2min),it covers20*120m.=2400m=2.4 km

CAR B(velocity =15m/s to west)

In 1s, it covers 15m.

In 120s, it covers 15*120m.=1800m=1.8km

Now, distance between the two cars after 2 minutes =2.4 km+1.8 km=4.2km
