Two friends A and B are running up hill and then to get down! length of road is 440 yards. A on his return journey met B going up at 20 yards from top, A has finished the race 5 minutes earlier than B, then how much time A had taken to complete the race.
[ "A)51.5minutes", "B)52.5minutes", "C)53.5minutes", "D)54.5minutes" ]
B
When A travels 460m (=440+20), B travels 420m (=440-20). So, ratio of speed = 460:420 = 23:21. Let A's speed be 23x, and that of B's be 21x. 23x = ((2*440) / t) which implies 23t = 880/x; 21x = ((2*440) / (t+5)) which implies 21(t+5) = 880/x. From these two equations, 23t = 21(t+5).
