Highway 199 is 85.3 miles long. That is 7.2 miles longer than Route 32. What is the length of Route 32? Write and solve an equation to find the answer, using r as a variable to stand for the length of Route 32.
To find the length of Route 32, we need to set up an equation based on the given information.
Let r be the length of Route 32 in miles.
According to the problem, Highway 199 is 7.2 miles longer than Route 32. Therefore, the length of Highway 199 can be represented as r + 7.2.
We also know that Highway 199 is 85.3 miles long.
So, we can write the equation as:
r + 7.2 = 85.3
To solve for r, we can subtract 7.2 from both sides of the equation:
r + 7.2 - 7.2 = 85.3 - 7.2
r = 78.1
Therefore, the length of Route 32 (r) is 78.1 miles.
