Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. bernard works for a business that sells and repairs tires. he can repair 24 tires in an 8 hour work day. what is bernard’s unit rate for the number of tires repaired in one hour? (\bigcirc \frac{3 \text{tires}}{1 \text{hour}}) (\bigcirc \frac{24 \text{tires}}{8 \text{hours}}) (\bigcirc \frac{8 \text{tires}}{1 \text{hour}}) (\bigcirc \frac{24 \text{tires}}{1 \text{hour}})

Explanation:

Step1: Recall unit rate formula

Unit rate is total quantity divided by total time, so formula is $\text{Unit Rate} = \frac{\text{Total Tires Repaired}}{\text{Total Hours Worked}}$.

Step2: Substitute values

Total tires = 24, total hours = 8. So $\text{Unit Rate} = \frac{24}{8}$.

Step3: Simplify the fraction

$\frac{24}{8} = 3$, so unit rate is $\frac{3}{1}\ \frac{\text{tires}}{\text{hour}}$.

Answer:

A. $\frac{3}{1}\ \frac{\text{tires}}{\text{hour}}$
