Drew is driving a boat with the current speed of the water at 5 mph. He rode for 2 hours. Drew made the same trip in 1 hour with no current. How fast is Drew traveling in still water?
***
let x=speed of boat in still water
x-5=speed of boat against the current
travel time*speed=distance
..
2(x-5)=1*x
2x-10=x
x=10
How fast is Drew traveling in still water? 10 mph
