Movie Math

What do movies have to do with mental math? You might think of times, ticket prices, salaries, etc. In fact, many people use mental math all the time to solve problems. What about teenagers? If faced with a dilemma regarding a movie and your curfew, could you also use mental math to get yourself out of trouble?

Movie Mania

The latest blockbuster is out! You have tickets for the 7:30 show. The movie is 150 minutes long and the theater is 20 minutes from your house. Will you make it home in time for your 10:30 curfew?

The movie is 150 minutes. There are 60 minutes in 1 hour, so 150 minutes is 2 hours and 30 minutes. You can add that to the start time of the movie:

7:30+2:30=10:00

The movie will end at 10 p.m. Since your home is 20 minutes from the movie, you should get home around 10:20—before your curfew!

There are many tricks you can learn to help you with mental math problems that you might face. See for yourself: http://youtu.be/qU26jj4MM_A
