Question

The depth of the water in Jeanne's hot tub varies directly with the number of minutes that the faucet is turned on. At 8.15 A.M Jeanne's started filling her circular hot tub with water. At 8.59 A.M there was a foot of water in the tub. When will the hot tub have 2 3/4 feet of water in it?

A.11:15 A.M
B.10:59 A.M
C.10.15 A.M
D.10:16 A.M

Can someone explain to me how to solve.

Answer 1

To raise the water level 1 foot took 44 minutes
so to raise it 2.75 ft will take 44(2.75) or 121 minutes
or 2:01 hrs

since she started at 8:15
it will be 2 3/4 ft deep at 8:15 + 2:01 or at 10:16
