Question

two persons moving p and q movind in opposite direction from one point with the velocities 12 m/s,7/s respectively then the distance between them is after 5seconds is​

Answer 1

Answer:

ANSWER

Since the two cars are moving in the same direction with same speed therefore relative speed between two cars is zero.

Let the relative speed of the third car be w.r.t the two cars.

Relative velocity of the third car:

(4/60)h

5km

=75km/h

Actual velocity of the third car:75−30=45km/h
