Question

Roger spends 1 hour 25 minutes doing homework, 1 hour swimming, and 30 minutes watching television each day. On average, how much time is spent on each activity each day?

a) 45 minutes
b) 50 minutes
c) 55 minutes
d) 60 minutes

Answer 1

To calculate the average time spent on each activity, you sum the total time spent across all activities and divide by the number of activities. After calculations, the average is approximately 58 minutes, but this doesn't match any provided answer choices.

Step-by-step explanation:

To find the average time Roger spends on each activity each day, we must first add the time spent on all activities and then divide by the number of activities.

1. Add the time spent on each activity: 1 hour 25 minutes + 1 hour + 30 minutes.
2. Convert the total time into minutes: (1 hour × 60 minutes/hour) + 25 minutes + (1 hour × 60 minutes/hour) + 30 minutes = 60 minutes + 25 minutes + 60 minutes + 30 minutes = 175 minutes.
3. Since there are three activities, divide the total time by 3 to find the average time spent per activity: 175 minutes ÷ 3 ≈ 58.33 minutes.
4. However, since the answer choices are in full minutes, we round to the nearest whole minute, resulting in an average time of 58 minutes per activity, which matches none of the answer choices provided.

It seems there might be an error in the provided answer choices because none of them matches the calculated average. Please review the question and the answer choices.
