Question

When you arrive at the family reunion, Uncle David has already started eating mini hot dogs. 2 minutes later, he has eaten a total of 22 hot dogs. 8 minutes after you arrived he finished 76 of them.

What is his rate?

  dogs per minute  

Answer 1

Hey Tony, here the trick is to classify time points and hot dog quantities after your arrival. At minute 2, Uncle David had eaten 22 hotdogs and at minute 8, he would have eaten a total of 76 hotdogs. So in order to calculate the rate (hotdogs/minute), take the difference of hotdogs and divided by the time difference. rate=(76-22)/(8-2)=9 hotdogs/minute
