The speed of a boat in still water is 16 km/h and the speed of the current is 4 km/h. How much distance can the boat cover upstream in 3 hours?
Correct Answer: Option D
Explanation:
Upstream speed = 16 - 4 = 12 km/h. Distance covered in 3 hours = 12 * 3 = 36 km.
Upstream speed = 16 - 4 = 12 km/h. Distance covered in 3 hours = 12 * 3 = 36 km.

Excluding stoppages, a transit truck travels at 75 km/h and including stoppages it travels at 62.5 km/h. How many minutes does the truck stop per hour?
Correct Answer: Option B
Explanation:
Stoppage time per hour = (75 - 62.5) / 75 = 12.5 / 75 = 1/6 hour. In minutes = (1/6) * 60 = 10 minutes.
Stoppage time per hour = (75 - 62.5) / 75 = 12.5 / 75 = 1/6 hour. In minutes = (1/6) * 60 = 10 minutes.
