The angle of revelation from the bottom of a scenic gondola rode to the top of a mountain is 22 degrees. If the vertical distance from the bottom to the top of the mountain is 689 feet and the gondola moves at a speed of 130 feet per minute how long does the ride last?

sinα=h/L L=h/sinα t=L/v t=h/(vsinα), we are given that h=689ft, v=130ft/min, and α=22° so t=689/(130sin22°) minutes t≈14.15 minutes (to nearest hundredth of a minute, in min:sec ≈ 14:09)
