Question 1091779: A small aircraft is traveling from Melbourne to Hobart, a distance of 597 kilometers. After 80 km the pilot radios control to report very bad weather over Bass strait. The plane has a cruising speed of 450 km/h and is set on autopilot. Given that wind and weather conditions may result in up to 20 minutes delay, how much time should the tower at Hobart allow to pass before they become concerned that the plane has encountered trouble

the plane has 597 - 80 = 517 kilometers to go.
traveling at 450 kilometers per hour, the plane should take approximately 517/450 = 1.15 hours to reach hobart if there wasn't any delay.
multiply 1.15 by 60 and that's equivalent to approximately 69 minutes.
add 20 minutes for the anticipated delay and the plane should arrive in hobart in approximately 89 minutes.
if the plane hasn't arrived by then, hobart should start becoming concerned.
