trent added water to a pool. it took 3 minutes to add 9 gallons of water. how long would it take to add 18 gallons of water to the pool? complete the table. gallons 9 18 minutes 3
Answer
Explanation:
Step1: Find the rate of water - adding
The rate is the amount of water added per minute. Given that 9 gallons are added in 3 minutes, the rate $r=\frac{9}{3}=3$ gallons per minute.
Step2: Calculate the time for 18 gallons
We know that rate $r = 3$ gallons per minute and the amount of water $a = 18$ gallons. Using the formula $t=\frac{a}{r}$, where $t$ is time. Substitute $a = 18$ and $r = 3$ into the formula, we get $t=\frac{18}{3}=6$ minutes.
