You observe a plane approaching overhead and assume that its speed is 700 miles per hour. The angle of elevation of the plane is 16° at one time and 58° one minute later. Approximate the altitude of the plane

During takeoff, an airplane's angle of ascent is 16° and its speed is 300 feet per second.
(a) Find the plane's altitude after 1 minute. (Round your answer to the nearest whole number.)
ft
(b) How long will it take the plane to climb to an altitude of 10,000 feet? (Round your answer to one decimal place.)
