Question

The movie you chose is 2 hours long. After only 1 /2 of an hour, you look and "Oh no!" you have already eaten a third of your popcorn! If you continue eating popcorn at this speed, do you think you will have enough for the rest of the movie? Include a mathematical explanation to support your thinking.

Answer 1

no

at every 30 minutes, a third of the popcorn is consumed.

After an hour, 1/3 + 1/3 = 2/3 of popcorn would be consumed.

At one hour 30 minutes, 2/3 + 1/3 = 3/3 or 1 or all of the popcorn would have been consumed

Explanation:

The rate at which popcorn is consumed is 1/3 in 30 minutes

so, in 1 and a half hours, all the popcorn would be finished

1/3 + 1/3 + 1/3 = 1
