A car covers 650 kmps in 12 hours and the other 850 kms in 18 hours. Find the average sped of the car ?

Solution (By Examveda Team)

$$\eqalign{ & {\text{Average speed}} \cr & = \frac{{{\text{Total distance }}}}{{{\text{Total time}}}} \cr & = \left( {\frac{{650 + 850}}{{12 + 18}}} \right)\,{\text{kmph}} \cr & = \left( {\frac{{1500}}{{30}}} \right)\,{\text{kmph}} \cr & \therefore {\text{Average speed}} = 50{\text{ kmph}} \cr} $$
