Answer 1

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

If The 1st car moves d at time of 60 mins

similarly the 2nd car moves d at the same time ..

so the net distension will be 2d
