Question

Lily walks 2 kilometers during each trip to school. Write an equation that shows the

relationship between the number of trips x and the total distance walked y.

Answer 1

y = 2x

Explanation:

Total distance walked = y

Number of trips = x

Lily walks 2 kilometers during each trip to school

Equation that shows the

relationship between the number of trips x and the total distance walked y:

y = 2x

For example, if the number of trips (x) is 3

Total distance walked,y = 2(3)

y = 6 kilometers
