Boats and Streams MCQs

Boats and Streams MCQs are quantitative aptitude problems about the speed of a boat or swimmer moving with or against a water current. They are common in NTS, ISSB, SSC and bank tests. Every question comes with an instant answer, so you can check each calculation and build speed with the standard formulas.

Question 01 Boats and Streams

What is the speed of the boat in still water? I. The boat covers a distance of 48 kms in 6 hours while running upstream. II. The boat covers the same distance in 4 hours while running downstream.

About Boats and Streams MCQs

Boats and Streams is a branch of speed, time and distance. If a boat's speed in still water is u and the stream's speed is v, the downstream speed is u + v and the upstream speed is u minus v. Questions ask you to find the still water speed, the stream speed, the time for a journey, or the distance of a round trip completed in a given time. Some problems compare distances covered with and against the stream in equal time. Once the two basic formulas are clear, most questions can be solved in under a minute.

Frequently asked questions

How do you find the speed of a boat in still water?

Add the downstream and upstream speeds and divide by two. For example, if a boat travels at 24 km/h downstream and 20 km/h upstream, its speed in still water is (24 + 20) ÷ 2 = 22 km/h. The stream speed is (24 minus 20) ÷ 2 = 2 km/h.

Which exams ask Boats and Streams MCQs?

These questions appear in the quantitative sections of NTS, GAT, ISSB and armed forces initial tests in Pakistan, SSC CGL, SSC CHSL, IBPS PO, SBI PO and RRB NTPC in India, and BCS and bank job exams in Bangladesh. Campus placement aptitude rounds use them too.
