# Distance Between Two Places in Water Calculator

Even though the distance between two places in water are same but the time taken to reach the places will differ depending on the speed of the stream. Here is the online distance between two places in water calculator which helps you to find the distance within the fraction of seconds. This distance between two places in upstream and downstream calculator requires values of speed in still water, the speed of stream and time taken to reach as inputs.

## Distance Between Two Places in Upstream and Downstream Calculator

Even though the distance between two places in water are same but the time taken to reach the places will differ depending on the speed of the stream. Here is the online distance between two places in water calculator which helps you to find the distance within the fraction of seconds. This distance between two places in upstream and downstream calculator requires values of speed in still water, the speed of stream and time taken to reach as inputs.

#### Formula:

Distance between two places (km) = ((a^{2} - b^{2})t) / 2a
**Where,**
a = Speed in still water (km/hr)
b = Speed of stream (km/hr)
t = Time taken to reach place A than place B (hours)

### Example:

Calculate the distance between two places in water with speed in water of 40 km/hr, speed of stream of 30 km/hr and time taken to reach place A than place B of 2 hours.

#### Solution:

Distance Between Two Places In Upstream And Downstream = ( ( 40^{2} – 30^{2} ) 2 ) / 2 x 40

= 17.5 km
