A boat travels between two riverside cities, A and B, located 21 miles apart. The river flows in the direction from A to B at 2 mph. The boat takes a total of 10 hours to make a round trip from A to B and back to A again. How long does it take the boat to make the one-way trip from A to B if the boats speed remailer constant relative to the speed of the river in each direction

The time taken by the boat to make the one-way trip from A to B = 3 hrs

Explanation:

Distance between A & B = 21 mile

Velocity of river ( v ) = 2

Total time taken ( T )= 10 hours

By solving above equation we get

u = 5

The time taken by the boat to make the one-way trip from A to B

T = 3 hours

This is the time taken by the boat to make the one-way trip from A to B.

im not to sure what it is

the answer would be 32*f
