# Speed of Man in Still Water Calculator

The speed of a boat in still water can be calculated by comparing the time taken to cover a distance in upstream and downstream. Here is the simple online speed of man in still water calculator which fetches you the speed of boat based on the entered input values of time taken to cover distance at upstream, the time taken to cover distance at downstream and stream speed. The speed values should be entered in the km/hr units. This simple tool can provide you highly reliable results.

#### Formula:

Speed of man in still water (km/hr)= ((b + a) / (b - a)) x c
**Where,**
a = Time taken to cover distance at downstream (hours)
b = Time taken to cover distance at upstream (hours)
c = Speed of stream (km/hr)

### Example:

Calculate the speed of man in still water with the time taken to cover distance at upstream of 8 hrs and time taken to cover distance at downstream of 5 hrs and speed of the stream of 10 km/hr.

#### Solution:

Speed of man in still water = ( ( 8 + 5 ) / ( 8 – 5 ) ) x 10

= ( 13 / 3 ) x 10

= 43.333333 km/hr
