Raju and Sajan travels at speeds of ratio 2:3. If Raju takes 20 minutes more to reach the destination find the time taken by Raju to reach the destination?
Ratio of speed=2:3,
Ratio of time taken=3:2
Suppose Raju takes 3t hours and Sajan takes 2t hours,
then 3t-2t = 20/60=1/3
Time taken by Raju=3t=3*1/3=1 hour
