Question

A leaky faucet drips 56 cubic inches of water in 2 hours. At the same rate, how many cubic inches of water will drip in 7 hours??? A. 110 cubic inchesB. 196 cubic inchesC. 280 cubic inchesD. 392 cubic inches

Answer 1

Let's begin by identifying key information given to us:

Volume of water = 56 in^3

Time = 2 hours

`\begin{gathered} V=56in^3 \\ t=2hrs \\ \end{gathered}`

To calculate how much volume of water will drip after 7 hours, we use simple proportion as shown below

`\begin{gathered} 56in^3=2hrs \\ x=7hrs \\ \text{Cross multiply, we have:} \\ 2x=7\cdot56 \\ (2x)/(2)=(7\cdot56)/(2) \\ x=196in^3 \end{gathered}`

At 7 hours, the amount of water to have dripped will be 196 cubic inches.

Hence, option B is the correct answer
