Mitchel ate 45 hotdogs in 3 minutes at the annual hotdog eating contest. What is Mitchel unit rate?

15 hotdogs per minute.

45 : 3 = 15.

3 x 15 = 45.

Unit rate means how many hot dogs per 1 minute. so we know 45 hotdogs/3 minutes is the same ratio as x hotdogs/1 minute.

45/3 = x/1. now cross multiply to get

45=3x. now solve for x

15 = x.

The unit rate was 15 hotdogs per minute. that's some record!
