    No need to have a fear of math, just jump into our word problem question of the week and let us know how you solve it. Take your time and work it out, then check below to compare your solution to ours. Happy mathing!

    Question: Noelle spends 40 minutes each day playing the violin. She spends 45 minutes each day playing the guitar. If Noelle doesn’t play any other musical instruments, then how much time does she spend each week not playing an instrument? Give your answer in hours and minutes.

     

    Solution: Since 40 minutes + 45 minutes = 85 minutes = 1 hour and 25 minutes, Noelle spends 24 hours – 1 hour and 25 = 22 hours and 35 minutes not playing an instrument in a day. To find out how much time that is in a full week, we can multiply the hours and minutes by 7 separately: 22 hours × 7 = 154 hours and 35 minutes × 7 = 245 minutes = 4 hours and 5 minutes. So, in total, Noelle spends 158 hours and 5 minutes each week not playing a musical instrument.

    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.
