A train 250 meters long takes 30 seconds to cross a man running at 6 km/h in the opposite direction. Find the speed of the train.
Correct Answer: Option D
Explanation:
Relative speed = 250 / 30 = 25/3 m/s = (25/3) * (18/5) = 30 km/h. In opposite directions, Relative Speed = Speed of train + Speed of man => 30 = Speed of train + 6 => Speed of train = 24 km/h.
Relative speed = 250 / 30 = 25/3 m/s = (25/3) * (18/5) = 30 km/h. In opposite directions, Relative Speed = Speed of train + Speed of man => 30 = Speed of train + 6 => Speed of train = 24 km/h.

A man covers a distance of 24 km in 3 hours. If he doubles his speed, how much time will he take to cover a distance of 32 km?
Correct Answer: Option C
Explanation:
Original speed = 24 / 3 = 8 km/h. Doubled speed = 16 km/h. Time required for 32 km = 32 / 16 = 2 hours.
Original speed = 24 / 3 = 8 km/h. Doubled speed = 16 km/h. Time required for 32 km = 32 / 16 = 2 hours.
