A Boeing 747 jet takes off from Boston's Logan Airport, which is at sea level, and climbs to a cruising altitude of 27,000 ft at a constant rate of 1400ft/min.

Question

A.) write a linear equation for the height of the plane in terms of the time after takeoff.
B.) use your equation to find the height of the plane 14 min after takeoff.

Answer 1

height = 1400t , for 0 ≤ t ≤ 19.29

b)
when t - 14
height = 1400(14) = 19600
