A man takes 50 minutes to cover a certain distance at a speed of 6 km/hr. If he walks with a speed of 10 km/hr, he covers the same distance in
(a)10 minutes
(b)20 minutes
(c)30 minutes
(d)40 minutes
Answer
Explanation
Distance = Speed × Time $=\left(6 \times \frac{50}{60}\right) \mathrm{km}=5 \mathrm{km}$. $$\text { ∴ } \text { Required time }=\frac{\text { Distance }}{\text { Speed }}=\left(\frac{5}{10}\right) \mathrm{hrs}=\frac{1}{2} \mathrm{hr}=30 \mathrm{min} .$$
