The first car went through 32.5 gallons and the second car went through 37.14 gallons of gas.
To solve this problem we will start by calculating time needed for each of them to fill the pool.
We have formula:
Volume = rate * time
Or
time = volume / rate
Wilma:
time = 9900 / 900
time = 11h
Betty:
time = 9900 / 500
time = 19.8h
Now we substract these two numbers:
time_difference = 19.8 - 11 = 8.8h
Betty needs 8.8 hours more than Wilma to fill the pool.
2,508 divided by 152 is equal to 16.5
I say 17 minutes, since 152x16=2,432 so a extra minute is needed to get to 2,508
You can tell that a fraction is a unit fraction when it is over a unit of one. This is also known as unit rate.
