A boat running upstream takes 8 hr 48 min to cover a certain distance, while it takes 4 hrs to cover the same distance running downstream. What is the ratio b/w speed of boat & speed of water current?
Upstream Time = 8 hours 48 min or 44/5 hours
Downstream Time = 4 hours
The ratio of Upstream Speed & Downstream Speed = 44/5: 4 or 11: 5
The only option satisfying the above ratio is an option (C).
The answer is an option (C)
