− | The percentage of her time spent in meetings is the total amount of time spent in meetings divided by the length of her workday.
| |
− | | |
− | The total time spent in meetings is <math>45 \text{ min} + 2*45\text{ min} = 2\text{ hours } 15 \text{ min} = 9/4 \text{ hours}</math>
| |
− | | |
− | Therefore, the percentage is <cmath>\frac{9/4 \text{ hours} }{9 \text{ hours}} = \frac{1}{4} = 25 \% = {(C)} 25}</cmath>
