Question

A person has to travel 300 km in 10 hours. If he travels one-third of the distance in half of the given time, then what should be the speed of that person so that he covers the remaining distance in remaining time?

• A. 30 km/hr
• B. 20 km/hr
• C. 10 km/hr
• D. 40 km/hr

Answer 1

Answer:

D. 40 km/hr

Distance travelled = 1/3 × 300 = 100 km Time required = 1/2 of 10 = 5 hours Remaining distance = 300 - 100 = 200 km Remaining time = 10 - 5 = 5 hours required speed = 200/5 = 40
