Its a scalar quantity which means it is defined only by magnitude. The upstream speed of boat was 10 kmhr whereas the downstream speed is 20 kmhr. Calculate the tarpons average speed like this.
The average speed of a body in a certain time interval is the distance covered by the body in that time interval divided by time.
Downstream speed 20 kmhr. A bluefin tunas formula would look like this. A boat travels equal distance upstream and downstream. So if a particle covers a certain distance s in a time to then the average speed of the body is.
