Question

Elizabeth recently bought a new bike, and she has started biking to and from work. The round-trip distance is 9 kilometers. Write an equation that shows the relationship between the number of round trips, x, and the total number of kilometers Elizabeth has biked, y. y=

Answer 1

The total distance Elizabeth bikes can be expressed as a product of the number of round trips and the distance of each round trip. Since each round trip is 9 kilometers, the equation that shows the relationship between the number of round trips, \(x\), and the total number of kilometers biked, \(y\), is:

\[ y = 9x \]

Here, \(y\) represents the total kilometers biked, and \(x\) represents the number of round trips.
