Average speed equals Total distance travelled upon total time taken
Therefore, final distance minus initial distance upon time
Final distance - initial distance =60-50=10 km
and the total time = 4 hrs
Therefore,10/4=2.5 km/hr
Therefore, final distance minus initial distance upon time
Final distance - initial distance =60-50=10 km
and the total time = 4 hrs
Therefore,10/4=2.5 km/hr
