Question

bernard works for a business that sells and repairs tires. he can repair 24 tires in an 8 hour work day. what is b the number of tires repaired in one hour?
24 tires / 8 hours
24 tires / 1 hour
3 tires / 1 hour
8 tires / 1 hour

Explanation:

Step1: Calculate tires repaired per hour

Use the formula: rate = $\frac{\text{total tires}}{\text{total hours}}$. Here, total tires = $24$, total hours = $8$. So rate = $\frac{24}{8}$.

Step2: Simplify the fraction

$\frac{24}{8}=\frac{24\div8}{8\div8}=\frac{3}{1}$. So the rate is $\frac{3\ \text{tires}}{1\ \text{hour}}$.

Answer:

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