Answer 1

Answer: the average reading time for the entire book club each day is 55 minutes.

Step-by-step explanation: To calculate the average reading time for the entire book club each day, we need to find the total reading time for all the members and divide it by the total number of members.

Given information:

Number of people who read for 65 minutes: 10

Number of people who read for 35 minutes: 15 - 10 = 5

Calculating the total reading time:

Total reading time for the 10 people who read for 65 minutes each day: 10 * 65 = 650 minutes

Total reading time for the 5 people who read for 35 minutes each day: 5 * 35 = 175 minutes

Calculating the average reading time:

Total reading time for the entire book club: 650 + 175 = 825 minutes

Average reading time per person per day: 825 / 15 = 55 minutes

Therefore, the average reading time for the entire book club each day is 55 minutes.

Answer 2

To find the average reading time for the entire book club, we need to calculate the total reading time for all the people and then divide it by the total number of people.

For the 10 people who read for an average of 65 minutes each day, the total reading time is 10 * 65 = 650 minutes.

For the remaining 15 - 10 = 5 people who read for an average of 35 minutes each day, the total reading time is 5 * 35 = 175 minutes.

The total reading time for the entire book club is 650 + 175 = 825 minutes.

To find the average reading time, we divide the total reading time by the total number of people: 825 / 15 = 55 minutes.

Therefore, the average reading time for the entire book club each day is 55 minutes.
