A boat can row 8 km/h in still water. If the river velocity is 4 km/h, find the distance covered downstream by the boat in 45 minutes.
A. 8 km
B. 12 km
C. 9 km
D. 10 km

Correct Answer: Option C


Explanation:
Downstream speed = 8 + 4 = 12 km/h. Time = 45 minutes = 45/60 = 3/4 hour. Distance covered = Speed * Time = 12 * (3/4) = 9 km.
