Step-by-step explanation:
To find the average time spent on each activity, we need to add up the time for each activity and then divide it by the number of activities.
1 hour 25 minutes + 1 hour + 30 minutes = 2 hours 55 minutes
Next, we divide the total time by the number of activities:
2 hours 55 minutes ÷ 3 = 58 minutes
So, on average, Roger spends approximately 1 hour and 58 minutes on each activity per day.
