The ratio between the speeds of the A and B is 2:3, and therefore A takes 10 min more than the time taken by B to reach the destination. If A had walked at double the speed, he would have covered the distance in Answers.
A) 15 min B) 16 min C) 14 min D) 18 min E) 19 min
Ratio of speed = 2:3   Ratio of time = 3:2   15 min takes 10 min more   3x-2x = 10 min   15 min time=30 min   -&gt; covers the distance in 30 min , if its speed is x   -&gt; He will cover the same distance in 15 min, if its speed   doubles (i.e 2x)
