A car covers a distance from town 1 to town 2 at the speed of 56 km/hr and from town 2 to town 1 at the speed of 53 km/hr. What is the average speed of the car ?

Solution (By Examveda Team)

Average speed :
$$\eqalign{ & = \left( {\frac{{2 \times 56 \times 53}}{{56 + 53}}} \right){\text{km/hr}} \cr & = \left( {\frac{{5936}}{{109}}} \right){\text{km/hr}} \cr & = 54.45{\text{ km/hr}} \cr } $$
