Hi Anurag you posted a question on the two cars moving in same direction with same velocity 30km/hr , but how can the third car meet both cars after the given time interval if both have same velocity and have 5m of initial distance.
Plz. approve my answer by clicking Yes given below, if u loved it... Plz/....
And please reply if the question is to be edited
BEST OF LUCK!
Firstly,it,s not my question.It was asked in a test by my teachers.Initially, the cars were moving with a speed of 30 KM/h(in the same direction ) by maintaining a constant difference of 5KM with respect to each other i.e 1st and 2nd car.Secondly, the 3rd car is not meeting the 1st car and 2nd car simultaneously from the opposite direction(since there is sufficient time gap between them).
velocity of A wrt C = va-vc
at time t=0 car C met car B
at t=4/60 hrs. car A will meet Car C.
distance traveled by Car A = 5km
=> 5= (Va-Vc)4/60
300/4= 30- Vc
75- 30 = - Vc
Vc = -45 kmph. (- shows opposite direction)
all the best!
