“There is geometry in the humming of the strings, there is music in the spacing of the spheres.” -Pythagoras

Math and music go hand in hand, even when you’re solving practical, real life math problems  such as the one we have for you in this week’s word problem challenge. Use your multiplication, subtraction, and other important elementary school real life math skills to solve the challenge below. Don’t forget to check back tomorrow for the solution!

Challenge: Eight students are performing songs for their music class recital. Each song is 5 minutes long. If each music student performs 1 song and all 8 students must be done performing by 9:15 PM, then what is the latest time they can start the recital?

Solution: The amount of time it takes for all of the students to finish their songs is 8 × 5 = 40 minutes. Since they have to finish the recital by 9:15 PM, we count back 40 minutes before 9:15 PM to 8:35 PM.

Before I came to Mathnasium, I could sum up everything I felt about math in one word: 'EVIL!' I hated math. ... Mathnasium has been my safe haven. They truly have shown me the light when it came to addressing my fear and provided me with the tools that I need to rebuild my prior knowledge so that I won't forget it. Math is no longer a subject I shy away from but it is a subject I can boldly accept and understand.
