Question

There are 15 people in a book club. Ten people read for an average of 65 minutes each day. The remaining people read for an average of 35 minutes each day. What was the average reading time for the entire book club each day? Enter your answer in the box.

Answer 1

10 people read 65 min
5 read 35
65+35= 100
so an hour and 40 min

Answer 2

10 x 65 = 650
5 x 35 = 175
650 + 175 = 825
825/15= 55

The answer is 55 minutes a day
