Answer 1

Given :

Ruben put an empty cup underneath a leaking faucet.

After 1 ½ hours, Ruben had collected ¼ cup of water.

To Find :

The rate, in cups per hour, at which the water is leaking from the faucet.

Solution :

Rate in which cup is filling with water.

$R=\dfrac{Portion\ of \ water \ filled }{Time\ taken}\\\\R = \dfrac{\dfrac{1}{4}}{1\dfrac{1}{2}}\\\\R= \dfrac{1\times 2}{4\times 3}\\\\R = 0.167 \ cup/hour$

Therefore, the rate is 0.167 cup/hour.
