Question

A man is travelling by car at the rate of 40 km/hr After every 80 km he rests for 20 min How long will he take to cover a distance of 240 km?

• A. 6 hr 40 min
• B. 6 hr
• C. 6 hr 20 min
• D. 7 hr

Answer 1

The correct option is A 6 hr 40 min

Rest time =$Numberofrest\times Timeforeachrest$
$=2\times 20=40min.$
Speed=40 Km/hr
Distance=240 Km.
$Time=\frac{Distance}{Speed}$
$\Rightarrow \frac{240}{40}=6Hours$
Total time to cover 240 Km=6 hr 40 min
