Q. Juan delivers papers every morning before he goes to school. He has to have all the papers delivered by 6:30 am. He has 86 papers and he figures it takes him an average of one and one half minutes to deliver each paper. At what time must he start in order to be done as close to 6:30 am as possible.
.
A. Do I divide 6:30 am by 86?
4:31
No, you do not need to divide 6:30 am by 86. To determine the start time, you need to consider the number of papers Juan has to deliver and the average time it takes to deliver each paper.
Since Juan has 86 papers and it takes him an average of 1.5 minutes to deliver each paper, you need to calculate the total time it will take him to deliver all the papers.
Total time = Number of papers * Average time per paper
Total time = 86 * 1.5 minutes
Total time = 129 minutes
Next, you need to subtract the total time (129 minutes) from the desired delivery time of 6:30 am.
6:30 am - 129 minutes = 4:21 am
So, Juan must start delivering the papers at 4:21 am in order to be done as close to 6:30 am as possible.
No, you do not divide 6:30 am by 86. To determine the time Juan must start delivering papers, we need to calculate the total time it will take for him to deliver all 86 papers at an average of one and a half minutes per paper, and then subtract that total from 6:30 am to find the desired start time. Here's how:
1. Calculate the total time it will take Juan to deliver all 86 papers:
- Multiply the number of papers (86) by the average time it takes to deliver each paper (1.5 minutes): 86 * 1.5 = 129 minutes.
2. Convert the total time to hours and minutes:
- Divide the total minutes by 60 to get the number of hours: 129 / 60 = 2 hours and 9 minutes.
- Since we're limited to 60 minutes in an hour, we'll express the time as 2 hours and 9 minutes.
3. Subtract the total time from 6:30 am to find the start time:
- Subtract 2 hours and 9 minutes from 6:30 am:
- Subtract the hours: 6 - 2 = 4 am.
- Subtract the minutes: 30 - 9 = 21 minutes.
- Therefore, Juan must start delivering papers at 4:21 am in order to be done as close to 6:30 am as possible.
No.
86 * 1.5 = 129 minutes = 2 hours and 9 minutes
6:30 - 2 hours, 9 minutes = ?
