the angle of elevation from the bottom of a scenic gondola ride to the top of a mountain is 31 degrees. if the vertical distance
Eduardwww [97]

Answer:

The ride lasts 10 minutes.

Step-by-step explanation:

The triangle that is formed is attached.

In order to find out how long the ride lasts, we need to figure out the horizontal distance d.

From trigonometry we have:

tan(31^o)=\frac{902}{d}.

Therefore

d=\frac{902\:feet}{tan(31^o)}=1501\:feet.

Now the amount of time t the gondola ride lasts is equal to the distance d divided by the speed of the gondola:

t=\frac{1501ft}{155ft/sec} =\boxed{9.69\:minutes.}

To the nearest minute this is 10 minutes.
