Question

Jennie plays two instruments, guitar and piano. She spends 4 hours playing guitar for every 3 hours she spends playing piano. If she spent 49 hours last month playing instruments, how long did she spend playing piano?

A) 21 hours
B) 28 hours
C) 36 hours
D) 42 hours

Answer 1

Jennie spent approximately 65.33 hours playing piano.

Step-by-step explanation:

To find the amount of time Jennie spent playing piano, we can set up a ratio using the given information. Let's let x represent the time she spent playing piano. Since she spends 4 hours playing guitar for every 3 hours playing piano, we can set up the ratio: 4/3 = x/49. Now we can solve for x by cross-multiplying and dividing: (4 * 49)/3 = x. Simplifying, we get x = 196/3, which is approximately equal to 65.33. Therefore, she spent approximately 65.33 hours playing piano.
