Question

A roller coaster is being built with a very steep drop and falls 64 feet over a horizontal distance of 160 ft.
a. What is the percentage grade of this drop? Round to the nearest tenth of a percent.
I did 64/160 = .4 so as a percentage that is 40%

b. What will the actual length of the track be in this section? Round to the nearest tenth of a foot.
I used the pythagorean theorem so 64^2 + 160^2 = c^2 then took the square root of that and got 172.3 feet


looks good
