A car maps a course distance of 240 km at an average speed of 60 km/h and handles the return trip at 40 km/h. Find the combined average speed.
Correct Answer: Option D
Explanation:
Average Speed = 2xy / (x + y) = (2 * 60 * 40) / (60 + 40) = 4800 / 100 = 48 km/h.
Average Speed = 2xy / (x + y) = (2 * 60 * 40) / (60 + 40) = 4800 / 100 = 48 km/h.

A boat moves upstream at 9 km/h and downstream at 15 km/h. Find the speed of the boat in still water.
Correct Answer: Option D
Explanation:
Speed in still water = (Downstream speed + Upstream speed) / 2 = (15 + 9) / 2 = 12 km/h.
Speed in still water = (Downstream speed + Upstream speed) / 2 = (15 + 9) / 2 = 12 km/h.

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 B
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.
