The distance is covered with the speed of P & Q are in the ratio of 5:6.P takes 30min more than Q to reach the destination.The time taken by P to reach the destination is.
Ratio of speed =5:6
Ratio of time = 6:5 because time and speed are inversly propotions So P takes 6x hrs,Q takes 5x hrs
then 6x-5x = 30/60 hr
x =1/2 hr
Time taken by P to reach the destination is 6x = 6* 1/2 = 3 hours
