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