Question

A fisherman can row upstream at 5 mph and downstream at 10 mph. He started rowing upstream until he got tired and then rowed downstream to his starting point. How far did the fisherman row if the entire trip took 6 ​hours?

Answer 1

I’m pretty sure the answer is 40 miles because the fisherman can row 5mph up stream and he can go 20m in 4h and he can go back down stream 10mph and go 20 miles in half the time (2h) he can row upstream. Hope this helps.
