A car covers the first 39 kms of its journey in 45 minutes and covers the remaining 25 km in 35 minutes. What is the average speed of the car?
(a)40 km/hr
(b)48 km/hr
(c)49 km/hr
(d)64 km/hr
(e)None of these
Answer
Explanation
Total distance travelled $=(39+25) \mathrm{km}=64 \mathrm{km}$. $$\begin{aligned} & \text { Total time taken }=(45+35) \mathrm{min}=80 \mathrm{min}=\frac{4}{3} \mathrm{hr} . \\ & \therefore \text { Average speed }=\left(64 \times \frac{3}{4}\right) \mathrm{km} / \mathrm{hr}=48 \mathrm{km} / \mathrm{hr} . \end{aligned}$$
