The current on the Mississippi River is a constant 4 miles per hour. A paddleboat travels 48 miles upstream in the same amount of time that it takes to travel 72 miles downstream. Find the speed of the boat in still water.

Downstream-68

Answer 2

Divide each mile amount by the speed of the current (48/4=12 and 72/4=18) add the two numbers (12+18=30)  The speed of the boat is 30mph
