Answer:
2 hours and 30 minutes.
Step-by-step explanation:
We have been given that after finishing her shift, a waitress wrote 2.5 under "hours worked" on her time card. We are asked to find the time she worked.
We will convert our given time into hours and minutes as:
[tex]2.5\text{ hours}=2\text{ hours}+0.5\text{ hour}[/tex]
[tex]2.5\text{ hours}=2\text{ hours}+\frac{1}{2}\text{ hour}[/tex]
We know that 1 hour equals 60 minutes, so we will substitute 60 minutes our equation as:
[tex]2.5\text{ hours}=2\text{ hours}+\frac{1}{2}\text{ hour}\times \frac{\text{60 minutes}}{\text{hour}}[/tex]
[tex]2.5\text{ hours}=2\text{ hours}+\frac{1}{2}\times \text{60 minutes}[/tex]
[tex]2.5\text{ hours}=2\text{ hours}+30\text{ minutes}[/tex]
Therefore, the waitress worked for 2 hours and 30 minutes.
