Question

A man has to cover a distance of 6 km in 45 minutes. If he covers one-half of the distance in $\frac{2}{3}{rd}$ time, what should be his speed to cover the remaining distance in the remaining time?

• A. 12 km/h
• B. 16 km/h
• C. 3 km/h
• D. 8 km/h

Answer 1

Answer: (A)

12 km/h

Answer 2

Remaining Distance to be covered $=6-\frac{1}{2}\times6=3$ km
Remaining time $=45-\frac{2}{3}\times45=15$ minutes (or) $\frac{1}{4}$ hour
Required speed to cover the remaining distance in the remaining time,
$=(\frac{\frac{3}{1}}{4})=12$km/h
Hence, option A is the correct answer.The correct option is (A): 12 km/h
