Question

Two cars are moving in the same direction at the
same speed u. The cars maintained a constant
distance x between them. An another car (third car)
coming from opposite direction meets the two cars
at an interval of 't'. Then find the speed of the third
car.
Options are in the attachment​

Answer 1

Answer:

i think option (2)x/y is correct

Answer 2

Since the cars are moving in the same direction with same speed u. Let's consider them to be stationary. So the relative speed of the car becomes v+u (where v is the speed of the third car).

Speed = Distance/Time

v+u=x/t

v=u-(x/t)
