Question

a construction crew has just built a new road. it took them 8 weeks to build 20.48 kilometers of road. at what rate did they build the road?
kilometers per week

Explanation:

Step1: Recall the formula \( d = rt \)

We know \( d = 20.48 \) kilometers (distance), \( t = 8 \) weeks (time), and we need to find \( r \) (rate). Rearrange the formula to solve for \( r \): \( r=\frac{d}{t} \)

Step2: Substitute the values into the formula

Substitute \( d = 20.48 \) and \( t = 8 \) into \( r=\frac{d}{t} \), so \( r=\frac{20.48}{8} \)

Step3: Calculate the division

\( \frac{20.48}{8}=2.56 \)

Answer:

2.56 kilometers per week
