Answer:
122.5 hotdogs could be eaten in 35 minutes.
It would take 10 minutes to eat 35 hotdogs.
Step-by-step explanation:
1. Note 21 hot dogs were eaten in 6 minutes.
2. 3.5 hotdogs are eaten per minute.
3. 35 times 3.5 = 122.5
4. 35 divided by 3.5 = 10
It would take Mike 10 minutes to eat 35 hotdogs. Mike can eat 122.5 hotdogs in 35 minutes.
21 hotdogs / 6 minutes = 3.5 hotdogs per minute
35 / 3.5 = 10 minutes
35 (3.5) = 122.5 hotdogs
