Question

A conveyor belt carries supplies from the first floor to the second floor, which is 22 feet higher. The belt makes a 60° angle with the ground. a. How long is the conveyor belt? Round your answer to the nearest foot. b. If the belt moves at 75 ft/min, how long does it take the supplies to move to the second floor? Round to the nearest tenth.

Answer 1

a) 44
`√(3)`/3 feet

b) .3 minutes

Explanation:

We know all three of the angles: 30 60 90. So we can divide 22 by
`√(3)`, and then multiply that number by 2. We cannot have a radicand in the bottom, so multiply the denominator and numerator by

for b), simply divide a) by 75 ft/min, which is approximately .3 minutes.
