# Boats and Streams – Aptitude Questions and Answers

**Boats and Streams Questions and Answers**

The subject matter of Boats and Streams Questions is quite essential as these questions are there in nearly all competitive exams from the topic. On this page we will discuss about Questions asked About the topic boats and streams.

Upstream
If Direction of boat and that of Flowing water is in opposite direction it's called upstream

Downstream
If Direction of boat and that of Flowing water is in same direction it's called downstream.

### Rules:

- When the speed of the boat or swimmer is ‘x’ km per hour and the stream’s speed is ‘y’ km per hour, then:
- The speed of the swimmer or boat upstream = (x – y) km per hour
- The speed of the swimmer or boat downstream = (x + y) km per hour

- In the stationary or still water
- The speed of the boat is given by = 1/2 (downstream speed + upstream speed)
- The speed of the stream is provided by = 1/2 (downstream speed – upstream speed)

- A certain distance in p1 hours is covered by a man when he rows downstream and comes back the equal distance upstream in p2 hours. If the stream’s speed is assumed as s km/hr, then the man’s speed in still water will be:

s = ( p2+ p1)/ ( p2-p1)km/hr

where ,

s = speed of man.

p2 = time taken to cover upstream

p1 = time taken to cover downstream
