Final answer:
Rachelle can walk 3.75 miles in 1 hour.
Step-by-step explanation:
To find out how far Rachelle can walk in 1 hour, we need to calculate the rate at which she walks. We know that she can walk 2.5 miles in 40 minutes. First, we'll convert 1 hour into minutes. There are 60 minutes in 1 hour, so we have 60 minutes. Now we can set up a proportion to find the distance she can walk in 1 hour:
2.5 miles / 40 minutes = x miles / 60 minutes
Cross-multiplying gives us:
40x = 2.5 * 60
Simplifying, we have:
40x = 150
Dividing both sides by 40, we find that x = 3.75. So, Rachelle can walk 3.75 miles in 1 hour.
