Answer: [tex]\frac{13}{10}[/tex] of an hour.
Step-by-step explanation:
1. You know that it is from 3:12 p.m. (48 minutes before 4:00 p.m.) to 4:30 p.m. (30 minutes after 4:00 p.m.)
2. Therefore, you must make the following addition:
[tex]48minutes+30minutes=78minutes[/tex]
This is 78 minutes out of 1 hour (60 minutes).
3. Therefore, you have the following fraction:
[tex]\frac{78}{60}[/tex]
4. Now, you must reduce the fraction:
[tex]\frac{78}{60}=\frac{13}{10}[/tex]
5. The answer is 13/10 on an hour.
