    Two cars A and B are moving with same speed of 45 km/h along same direction. If a third car C coming from the opposite direction with a speed of 36 km/h meets two cars in an interval of 5 min, the distance of separation of two cars A and B should be (in km)

    A)  6.75                      

    B)         7.25                      

    C)  5.55                      

    D)         8.35

    E)  4.75

    Correct Answer: A

    Solution :

    \[{{v}_{rel}}=45+36=81\,km/h=81\times \frac{5}{18}m/s\] \[{{s}_{rel}}={{v}_{rel}}\times t=81\times \frac{5}{18}\times (5\times 60)\] \[=\frac{81\times 5\times 5\times 60}{18}=6750m=6.75\,km\]
