A boats man can row in still water at speed of 7 km/hr. It takes 6 hours more to travel the same distance in upstream than in downstream if the speed of the river is 3 km/hr. what is the distance between the two destinations?	Choose the correct choice from the following options: A) 40 B) 87 C) 126 D) 18 E) 91
Explanation:   x = 7 km/hr ; y = 3 km/hr   Ds = 10 km/hr ; Us = 4 km/hr   Distance (d) is same. Therefore, if time taken for downstream is t hours, the time for upstream is (t + 6) hours.   10*t = 4*(t + 6)   6t = 24 ; t = 4 hours   d = 10*4=
