Question

An underground mine elevator descends 12% of the total depth every minute. The total depth of the elevator is 75 meters below the ground.

How many meters below the ground is the elevator after 2 minutes?

Answer 1

% means "per 100"

so 12% means "12 per 100" or (12/100)

"of" in this case means multiply, so we multiply

(12/100)*(75) to determine what 12% of 75 meters is

if it descends (12/100)*(75) meters per one minute, then for two minutes we just double that

so 2 * (12/100)*(75) --> plug that into a calculator and you'll have your final solution

Answer 2

thank you
