You can put this solution on YOUR website! an airplane is 75 miles directly behind a ship sailing a straight course. the rate of the airplane is 120 mph, and that of the ship is 20 mph. how long will it take the plane to overtake the ship?
--------------------------
The plane's speed relative to the ship is 100 mph (120 - 20).
75 miles/100 mph = 0.75 hours
----------------------
PS Both planes and ships use knots and nautical miles, not miles per hour.
