Answer:
The length of the tunnel is 7.66667 inch
Step-by-step explanation:
We are given
1 inch =60 miles
now, we can find for 1 mile
so,
60 miles = 1 inch
we get

we are given
total length is 460 miles
so, we can multiply both sides by 460

now, we can simplify it

So,
The length of the tunnel is 7.66667 inch
4y - 7 = 5 - 2y
Add 2y to both sides.
6y - 7 = 5
Add 7 to both sides.
6y = 12
Divide both sides by 6
y = 2
