A person row a boat 45 km downstream in 3 hours and manages the return journey upstream in 9 hours. Find the speed of the river current.
Correct Answer: Option D
Explanation:
Downstream speed = 45 / 3 = 15 km/h. Upstream speed = 45 / 9 = 5 km/h. Speed of current = (15 - 5) / 2 = 10 / 2 = 5 km/h.
Downstream speed = 45 / 3 = 15 km/h. Upstream speed = 45 / 9 = 5 km/h. Speed of current = (15 - 5) / 2 = 10 / 2 = 5 km/h.

A sound wave travels at a speed of 340 m/s. Find the distance covered by the wave in 10 seconds.
Correct Answer: Option C
Explanation:
Distance = Speed * Time = 340 * 10 = 3400 meters = 3.4 km.
Distance = Speed * Time = 340 * 10 = 3400 meters = 3.4 km.

Excluding stoppages, the speed of a train is 80 km/h and including stoppages, it is 60 km/h. For how many minutes does the train stop per hour?
Correct Answer: Option A
Explanation:
Stoppage time per hour = (Fast speed - Slow speed) / Fast speed = (80 - 60) / 80 = 20 / 80 = 1/4 hour. Converting to minutes = (1/4) * 60 = 15 minutes.
Stoppage time per hour = (Fast speed - Slow speed) / Fast speed = (80 - 60) / 80 = 20 / 80 = 1/4 hour. Converting to minutes = (1/4) * 60 = 15 minutes.
