The ratio between the speeds of the A& B is 2:3 an 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 ?
15mins
14mins
10mins
None of these
Explanation:
Ratio of speed = 2:3
Ratio of time = 3:2
A takes 10 min more
3x-2x = 10 min
A time=30 min
A covers the distance in 30 min , if its speed is x
He will cover the same distance in 15 min, if its speed
doubles (i.e 2x)
Ratio of speed = 2:3
Ratio of time = 3:2
A takes 10 min more
3x-2x = 10 min
A time=30 min
A covers the distance in 30 min , if its speed is x
He will cover the same distance in 15 min, if its speed
doubles (i.e 2x)
