The speeds of two bodies are in the ratio 5 : 6. If they clear the same sector distance, and the slower car takes 3 hours, how much time does the faster car take?
Correct Answer: Option D
Explanation:
Ratio of speeds = 5:6, so ratio of times taken = 6:5. Slower car takes 6 parts = 3 hours => 1 part = 0.5 hours. Time for faster car = 5 parts = 5 * 0.5 = 2.5 hours.
Ratio of speeds = 5:6, so ratio of times taken = 6:5. Slower car takes 6 parts = 3 hours => 1 part = 0.5 hours. Time for faster car = 5 parts = 5 * 0.5 = 2.5 hours.

A train running at 90 km/h overtakes a cyclist riding at 18 km/h in the same direction in 10 seconds. Find the length of the train.
Correct Answer: Option C
Explanation:
Relative speed = 90 - 18 = 72 km/h = 72 * (5/18) = 20 m/s. Length of train = Relative speed * Time = 20 * 10 = 200 meters.
Relative speed = 90 - 18 = 72 km/h = 72 * (5/18) = 20 m/s. Length of train = Relative speed * Time = 20 * 10 = 200 meters.

A person walking at 4 km/h covers a certain distance. If he runs at 8 km/h, he takes 30 minutes less to cover the same distance. Find the distance.
Correct Answer: Option B
Explanation:
Time difference = 30 minutes = 0.5 hours. Let distance be d. d / 4 - d / 8 = 0.5 => d / 8 = 0.5 => d = 4 km.
Time difference = 30 minutes = 0.5 hours. Let distance be d. d / 4 - d / 8 = 0.5 => d / 8 = 0.5 => d = 4 km.
