Paul is trying to set his alarm clock for tomorrow morning. He needs 30 minutes to get ready for school and it takes him 10 minutes to bike to school. If school starts at 8:40 a.m., and he would like to be 5 minutes early, what is the time he should set his alarm clock?
you add 30and 10 and then you sub tract that from the time and he eed to wake up at 8:00
To calculate the time Paul should set his alarm clock, we need to consider the time it takes him to get ready for school, his biking time to school, and the extra 5 minutes he wants to be early.
Step 1: Calculate the total time needed for preparation and biking:
The total time needed for preparation and biking is 30 minutes to get ready + 10 minutes to bike = 40 minutes.
Step 2: Add the extra 5 minutes to be early:
The total time with the extra 5 minutes is 40 minutes + 5 minutes = 45 minutes.
Step 3: Calculate the time to subtract from the school start time:
Since school starts at 8:40 a.m., we need to subtract the total time from this.
8:40 a.m. - 45 minutes = 7:55 a.m.
The time Paul should set his alarm clock is 7:55 a.m.
To determine the time Paul should set his alarm clock, we need to consider the time it takes for him to get ready and the time it takes to bike to school, along with the desired buffer time.
1. Start with the time school starts: 8:40 a.m.
2. Subtract the buffer time of 5 minutes: 8:40 a.m. - 5 minutes = 8:35 a.m.
3. Add the time it takes Paul to bike to school: 8:35 a.m. + 10 minutes = 8:45 a.m.
4. Add the time it takes Paul to get ready: 8:45 a.m. + 30 minutes = 9:15 a.m.
Therefore, Paul should set his alarm clock for 9:15 a.m.
he needs to get up 30+10+5 = 45 minutes before school
so, ...
