Question

24.) A helicopter is coasting at an elevation of 1,480 feet above the earth's surface. If the

helecopter descends 18 feet per minute, how many minutes will it take the helecopter to reach an
elevation of 472 feet? Write and solve an equation.

Answer 1

56 minutes

Step-by-step explanation:

first we'll use proportions

so if it descends 18 ft per minute, that's going to be
`(18)/(1)` and then we have to figure out how many feet it is that theyre descending so that's 1,480 - 472 and the answer is 1008

so thats how many feet it needs to descend

so we do
`(18)/(1)` =
`(1008)/(?)` so now we cross multiply

so 1008 = 18x

and then we divide 18 and we get x = 56

so it would take 56 minutes
