A train 150 meters long is tracking at a speed of 72 km/h. How long will it take to pass a bridge 250 meters long?
Correct Answer: Option B
Explanation:
Total distance = 150 + 250 = 400 meters. Speed = 72 * (5/18) = 20 m/s. Time taken = 400 / 20 = 20 seconds.
Total distance = 150 + 250 = 400 meters. Speed = 72 * (5/18) = 20 m/s. Time taken = 400 / 20 = 20 seconds.

A car covers a certain distance at 50 km/h. If the speed is increased to 75 km/h, it arrives 20 minutes earlier. Find the distance.
Correct Answer: Option B
Explanation:
Time difference = 20 minutes = 20/60 = 1/3 hour. Let distance be d. d / 50 - d / 75 = 1/3 => (3d - 2d) / 150 = 1/3 => d / 150 = 1/3 => d = 50 km.
Time difference = 20 minutes = 20/60 = 1/3 hour. Let distance be d. d / 50 - d / 75 = 1/3 => (3d - 2d) / 150 = 1/3 => d / 150 = 1/3 => d = 50 km.
