Kiran travels from A to B by car and returns from B to A by cycle in 7 hours. If he travels both ways by car he saves 3 hours. What is the time taken to cover both ways by cycle?

One Answer on this Question

1. x (A to B by car) + y (B to A by cycle) is 7 hours

   x (A to B by car) + x (B to A by car) is 7 minus 3 is 4 hours

   2x is 4 and hence x is 2

   2 + y is 7 and hence y is 5

   y (A to B by cycle) + y (B to A by cycle) is 5 + 5 is 10 hours
