An airplane leaves the Springfield airport and flies east at an airspeed of 300 miles per hour. It encounters a wind of 60 miles per hour from east to west. Which expression can be used to calculate the plane’s distance from Springfield h hours after takeoff?


D = (300 + 60)h


D = 300h – 60


D = 300h + 60


D = (300 – 60)h

D = (300 − 60)h

The 60 mph wind is a headwind (from east to west) so it reduces the plane’s ground speed to 300 − 60 = 240 mph, giving distance = 240h.
