Final answer:
Carla rode her skateboard 10 miles to the store, and half that distance again. The equation to find the total distance 'y' is y = x + (x/2), where 'x' is the initial distance. Plugging in 10 miles for 'x', the total distance 'y' is 15 miles.
Step-by-step explanation:
Carla enjoys riding her skateboard and rode her skateboard 10 miles to the store and then half that distance again. The equation to represent Carla's total distance is as the following:
y = x + (x/2)
In this scenario, 'x' represents the initial distance, which we know is 10 miles. Therefore, if we substitute 'x' with 10 miles in the equation, we get:
y = 10 + (10/2)
y = 10 + 5
y = 15 miles
Therefore, Carla's total distance 'y' is 15 miles.
