A runner covers a 400-meter track. The winner finishes in 40 seconds, while the runner-up takes 44 seconds. By what distance does the winner beat the runner-up? MCQ with Answer and Explanation

Explanation:
Time taken = Distance / Speed = 24 / 16 = 1.5 hours. Converting to minutes = 1.5 * 60 = 90 minutes.

Explanation:
Speed of first train = 120 / 10 = 12 m/s. Speed of second train = 120 / 15 = 8 m/s. Total distance to cross each other = 120 + 120 = 240 meters. Relative speed in opposite directions = 12 + 8 = 20 m/s. Time = 240 / 20 = 12 seconds.

Explanation:
Stoppage time per hour = (Fast speed - Slow speed) / Fast speed = (75 - 60) / 75 = 15 / 75 = 1/5 hour. Converting to minutes = (1/5) * 60 = 15 minutes.
