Question

1. modeling real life seven friends each run an equal part of a 5 - kilometer relay race. what fraction of a kilometer does each friend complete?

Explanation:

Step1: Identify total distance and number of friends

Total distance is 5 kilometers, number of friends is 7. We need to divide the total distance by the number of friends to find the distance each friend runs.
$$\text{Distance per friend} = \frac{\text{Total distance}}{\text{Number of friends}}$$

Step2: Substitute values into the formula

Substitute total distance = 5 km and number of friends = 7 into the formula.
$$\text{Distance per friend} = \frac{5}{7}$$

Answer:

$\frac{5}{7}$
