If Ava decides to reduce the time she does each activity by 16, find the total number of hours she spends studying and practicing in a year with a reasonable level of accuracy.

Answer 1

Answer:

398.88hours

Step-by-step explanation:

Note: If Ava decides to reduce the time she does each activity by 16minute I believe it should be

1. Ava spends 45min per day studying

    reduce this amount be 16min we have=45-16=29min

    in a year she will spend 365*29= 10585min

2. She also practices the piano for an average of 20 minutes per day

   reduce this amount be 16min we have=20-16=4min

    in a year she will spend 365*14= 5110min

3. She practices soccer 1.5 hours three times a week.

   in minutes 1.5hours is 90min three times a week

   in a day 90*3/7= 270/7=38.57

    reduce this amount be 16min we have=38.57-16=22.57min

    in a year she will spend 365*22.57= 8238.05min

in total for the year  she spends studying and practicing

=10585+ 5110+8238.05

=23933.05min to hours =23933.05/60

=398.88hours
