Asked by Sid

A salmon has to swim 25 miles upstream. It swims 7 miles each day and drifts back 5 miles each night. How may days it take for the salmon to first reach 25 mile mark?
Answered by Nathan
So the fish is moving 7 miles but falls back 5 miles each full day.

7-5= 2
25/2= 12.5

It would take the fish 12.5 days to move 25 miles.

The fish gains 2 miles per day.

After 9 days, it has gained 18 miles.
On day 10, it swims 7 miles and has made it to the 25-mile mark.
