Question

Jessica was told to practice playing the guitar for ½ of an hour per day. Jessica also spends ⅓ of an hour per day listening to guitar players. Jessica has already played ¼ of an hour today. How many hours does Jessica still need to play today?

a) 0.25 hours

b) 0.375 hours

c) 0.625 hours

d) 0.75 hours

Answer 1

Jessica still needs to play for 15 minutes today.

Step-by-step explanation:

To find out how many hours Jessica still needs to play today, we need to subtract the time she has already played from the total time she needs to practice. Jessica was told to practice for ½ of an hour which is equal to 30 minutes, and she has already played for ¼ of an hour which is equal to 15 minutes.

We can subtract 15 minutes from 30 minutes to find out the remaining time: 30 minutes - 15 minutes = 15 minutes. Therefore, Jessica still needs to play for 15 minutes today.
