Question

Frank swam kilometers against the current in the same amount of time it took him to swim kilometers with the current. The rate of the current was kilometer per hour. How fast would Frank swim if there were no current?

Answer 1

Answer:

If there was no current, Frank would swim at the same rate of kilometers per hour.

Explanation:

Given that Frank swam the same amount of kilometers against the current and with the current in the same time, then we realize that the current is a variable that does not affect Frank's swimming speed. So if there was no current, it would surely swim the same amount of kilometers at the same time.
