Once an airplane has reached its cruising altitude, its computer shows the destination to be 2,400 miles away. If the plane is traveling at a rate of 500 miles per hour, write a linear function of the distance d (in mi) the plane is from its destination t hours after reaching cruising altitude. d = How far (in mi) is the plane from its destination 2 hours after the flight begins? miles
