                                    2. 30 km/hr.

Problems on Time and Distance:

1. Excluding stoppages, the speed of a bus is 48 km/hr and including stoppages, it is 40 km/hr. For how many minutes does the bus stop per hour?
Solution:
                 Due to stoppages, it covers 8 km less.

                 Time to cover that 8 km = 8/48 *[60] 
                                                        = 10 minutes.

Solution:
                  The time ratio is 4: 2.
