Q12. A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream. What is the ratio between the speed of the boat and speed of the water current respectively?

• A. (a) 2:1
• B. (b) 3:2
• C. (c) 8: 3
• D. (d) cannot be determined

Answer 1

The correct option is C (c) 8: 3

Let the man's rate upstream be x kmph and that downstream be y kmph.

Then, distance covered upstream in 8 hrs 48 min = Distance covered downstream in 4 hrs.
