Problem 1: The ratio between the rates of traveling of A and B IS 2:3 and therefore A takes 10minutes more than the time taken by B to reach the destination. If A had walked at double the speed the time taken by him to reach the destination would have been?
Note: Speed and time are inversely proportion
A : B
S 2 : 3
T 3 : 2
Problem 2: A man is walking at a speed of 10km/hr. After every km, he takes rest for 4min. How much time will he take to cover a distance of 10km?
Total time=1 hour 36 min
Problem 3: A boy walks a certain distance and rides back taking a total time of 37min. I could walk both ways in 55min. How long would it take me to ride both ways?
