Suppose that the distance an aircraft travels along a runway before takeoff is given by D=(10/9)t^2​, where D is measured in meters from the starting point and t is measured in seconds from the time the brakes are released. The aircraft will become airborne when its speed reaches 400 km/h. How long will it take to become​ airborne, and what distance will it travel in that​ time?
