Question

Kyle is told that the distance between the lower waterfall and the upper waterfall in his favorite national park is about 1 1/2 miles. The distance between the falls on Kyle's map is about 1/2 inch. What is the unit rate calculated in miles per inch?

Answer 1

The unit rate calculated in miles per inch is 3 miles per inch.

Step-by-step explanation:

To find the unit rate calculated in miles per inch, we need to divide the distance between the lower waterfall and the upper waterfall (1 1/2 miles) by the distance between the falls on Kyle's map (1/2 inch).

So, the unit rate is 1 1/2 miles / 1/2 inch. To divide fractions, we invert the divisor and multiply.

1 1/2 miles / 1/2 inch = 1 1/2 miles x 2/1 inch = 3 miles / 1 inch.

The unit rate calculated in miles per inch is 3 miles per inch.
