A tugboat’s speed is 10 miles per hour with no current. A round trip to a loading dock 24 miles
away takes 5 hours. Find the speed of the current.
since time = distance/speed,
24/(10+c) + 24/(10-c) = 5
solve for c
away takes 5 hours. Find the speed of the current.
24/(10+c) + 24/(10-c) = 5
solve for c
