Answer:
Step-by-step explanation:
Because Bryce did 7/8 hours every day for 20 days,
7/8 hours is 52.5 minutes.
so then times 20, you will get 1050 minutes.
Then divided by 60(minutes per hour) you will get 17.5 hours,
which means she did 17 hours and 30 minutes in the first 20 days,
then you plus the last 1 hour per day for 10 days,
you will get 10 hours plus 17 hours and 30 minutes.
So Bryce have worked 27 and 30 minutes in september.
