Boat & Stream Problem Set 4

Hello Readers,

Boat and Stream questions are asked in almost all competitive exams. They are followed by simple tricks and calculations, and cover about 2-5% of the paper marks. Here is a sample paper sheet of the Boat and Stream based questions for your practice. Do give us a review.

Q1. A man can row 6 kmph in still water. If the speed of the current is 2 kmph, it takes 3 hours more in upstream than in the downstream for the same distance. The distance is:
(a) 30 km
(b) 24 km
(c) 20 km
(d) 32 km
(e) 28 km

Q2. A boat takes 9 hr to travel a distance upstream and takes 3 hr to travel the same distance downstream. If the speed of the boat in still water is 4 kmph, then what is the velocity of the stream?
(a) 4 kmph
(b) 3 kmph
(c) 6 kmph
(d) 2 kmph
(e) 8 kmph

Q3. A boat has to travel upstream 20 km distance from point X of a river to point Y. The total time taken by boat in travelling from point X to Y and Y to X is 41 min 40 s. What is the speed of the boat?
(a) 66 kmph
(b) 72 kmph
(c) 48 kmph
(d) Cannot be determined
(e) None of these

Q4. A steamer goes downstream from one port to another in 4 hr. It covers the same distance upstream in 5 hr. If the speed of the stream is 2 kmph, then find the distance between the two ports.
(a) 80 km
(b) 60 km
(c) 70 km
(d) 50 km
(e) 75 km

Q5. A boat running upstream takes 528 min to cover a certain distance, while it takes 240 min 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) 2 : 1
(b) 3 : 2
(c) 8 : 3
(d) 3 : 8
(e) 5 : 9
