A sound wave travels at a speed of 330 m/s. How much time will it take to travel a distance of 9.9 km?
Correct Answer: Option B

A train 150 meters long takes 20 seconds to cross a platform 250 meters long. Find the speed of the train in km/h.
Correct Answer: Option D
Explanation:
Total distance = 150 + 250 = 400 meters. Time = 20 seconds. Speed = 400 / 20 = 20 m/s. Speed in km/h = 20 * (18/5) = 72 km/h.
Total distance = 150 + 250 = 400 meters. Time = 20 seconds. Speed = 400 / 20 = 20 m/s. Speed in km/h = 20 * (18/5) = 72 km/h.
