Distance between 2 places A and B is given. A man P starts from place A at 9 pm and another man Q goes from B at 10pm . Speed of Q is double of that of P. Both cover 1/4 dist in the same time interval. then A travels the entire dist in time Select
A) 8hrs B) 9hrs C) 10hrs D) 11hrs E) 12hrs
let speed of p and q are x, 2x   time taken by 8hrs to cover 1/4 distance =t   x*t = 2x*(t-1)   t=2 for 1/4 of total distance   8hrs travels the entire dist in time 2*4=
