Final answer:
To estimate the distance from Kim's home to school, set up a proportion using the given information. Solve for x to find the estimated distance. The estimated distance from Kim's home to school is 0.75 miles.
Step-by-step explanation:
To estimate the distance from Kim's home to school, we can use a proportion. We know that Kim walks 1 mile in 20 min. We also know that she times the walk from home to school as taking 15 min. Let's set up the proportion:
1 mile / 20 min = x miles / 15 min
To solve for x, we can cross multiply:
20 min * x miles = 1 mile * 15 min
Dividing both sides by 20 min, we get:
x = (1 mile * 15 min) / 20 min = 0.75 miles
Therefore, the estimated distance from Kim's home to school is 0.75 miles.
