The hotdog eating champion, ate 13 hot dogs every 2 minutes at the county fair contest. how long did it take him to eat 91 hot dogs at the same rate?

They ate 13 hot dogs in 2 minutes, so divide 13 by 2 to find out how many hot dogs he ate in 1 minute:

13 / 2 = 6.5 hot dogs per minute.

Now divide total hot dogs eaten by 6.5 to get the total time:

91 / 6.5 = 14 total minutes.

First you calculate the rate for how many hotdogs he could eat per minute:

13 / 2 = 6.5

Now you must apply the same rate to 91:

91 / 6.5 = 14

Hope it helped,

Happy homework/ study/ exam!

There are 4 quarts in a gallon so the amount used can be shown as 4 1/4, or 4.25 so to find out how much gas is left in the tank you simply subtract 4.25 from 20.

20-4.25

=15.75

There is 15.75, or 15 3/4, gallons of gasoline left in the tank.
