Final answer:
To solve for how long it took Marcus to walk from the park to the store, we can set up and solve an equation using the information given.
Step-by-step explanation:
To solve for how long it took Marcus to walk from the park to the store, we can set up an equation using the information given. Let's say the time Marcus spent walking is represented by x minutes. Since Marcus ran 3 times as long as he walked, the time he spent running is 3x minutes. The total time spent walking and running is 24 minutes. So, the equation is:
x + 3x = 24
Simplifying the equation, we get:
4x = 24
To solve for x, we divide both sides of the equation by 4:
x = 6
Therefore, it took Marcus 6 minutes to walk from the park to the store.
