Understanding Proportional Relationships in Hot Dog Eating

The video tutorial explains how to determine the time it takes Mika to eat 35 hot dogs if she maintains a constant pace. It introduces the concept of constant pace, sets up a proportional relationship, and solves for the unknown variable using two different methods: hot dogs per minute and minutes per hot dog. The solution involves basic algebraic manipulation and simplification of fractions.

What is the initial problem Mika is trying to solve?

• How to increase her eating speed.

• How many hot dogs she can eat in one minute.

• How long it takes to eat 35 hot dogs at the same pace.

• How many hot dogs she can eat in 21 minutes.

What does it mean when the pace is constant?

• The number of hot dogs eaten decreases over time.

• The time taken to eat each hot dog increases.

• The number of hot dogs eaten per minute remains the same.

• The number of hot dogs eaten per minute changes.

How is the proportional relationship set up in the problem?

• By comparing the number of hot dogs eaten in different time intervals.

• By equating the ratio of hot dogs to time for different quantities.

• By calculating the average time per hot dog.

• By estimating the total time based on a guess.
