Alicia went on a steamboat ride up the Mississippi River. The boat travels 20 miles per hour in still water. How long will it take her to travel 60 miles upstream if the current of the river is 8 miles per hour?

Math 
Knights,
So since it is traveling 20 mph, but the current is going 8mph, the difference is 12mph that the boat is really traveling. 60mph / 12mph = 60/12 = 5 hours to get up the river.
