Question

Andrea ate 2 hot dogs in 20 minutes. At that rate, how many hot dogs would she eat in 3 hours?

Answer 1

The first step is to convert the hours to minutes, this way, it will be easier to solve this question (Remember 1 hour equals 60 minutes).

`3h\cdot(60\min)/(1h)=180\min`

Now, use this time to find the amount of hot dogs she would eat at the rate of 2 hot dogs in 20 minutes.

`180\min \cdot(2hotdogs)/(20\min)=18hotdogs`

She would eat 18 hot dogs in 3 hours.
