Explanation:

The reason behind this is that the water movement makes objects floating in its surface move at a certain rhythm. Generally, this measure is variable but after having the data of 400 m movement in 8 hours. We just have to divide to find out the speed at which the water moves the objects on its surface. We divide 400 between the 8 hours to obtain. 50 meters of distance advance in a single hour. Therefore in 4 hours and 25 minutes, it will be at the correct distance to be reached out and used.
