Question

i the conveyor belt takes 54 seconds to move gravel from the bottom of the conveyor belt to the tope at a rate of 3 feet per second, how high does the conveyor belt lift the gravel?

Answer 1

Usually conveyors are at an angle with the horizontal. Here for lack of more information, we assume that the conveyor is vertical (using pouches) to carry the gravel, or the 3 feet per second is measured vertically.

3 feet/second * 54 seconds
= 3*54 feet
=162 feet
