Question

A man is travelling by a car at $40\text{km/h}$. After every $80\text{km}$, he takes a break for $20\text{min}$. How long does he take to cover a distance of $240\text{km}$?

• A. $6\text{h}30\text{min}$
• B. $5\text{h}30\text{min}$
• C. $6\text{h}40\text{min}$
• D. $6\text{h}$

Answer 1

The correct option is C $6\text{h}40\text{min}$

Break time = Number of breaks * Time of each break
$=2\times 20=40\text{min}$
Time $=\frac{\text{Distance}}{\text{Speed}}=6\text{h}$
Total time to cover $240\text{km}=6\text{h}40\text{min}$
