The length of the tunnel is 460miles. If 1 inch represents 60 miles what is the length of the tunnel?

kotegsom [21]

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

$1mile=\frac{1}{60}inch$

we are given

total length is 460 miles

so, we can multiply both sides by 460

$460\times 1mile=460\times\frac{1}{60}inch$

now, we can simplify it

$460miles=7.66667inch$

So,

The length of the tunnel is 7.66667 inch
