The river is 137.5 miles long

Step-by-step explanation:

Using map scale, we can identify the proportionality between the actual distance between two places and the size on the map. To find the actual distance, we can multiply our scale (if in unit rate) by the real distance.

Therefore, we can multiply 25 by 5.5 to get the actual size of the river!

This is equal to 137.5 miles!

137.5 miles

Step-by-step explanation:

We can use ratios to solve

1 inch               5.5 miles

=

25 miles       x miles

Using cross products

1*x = 25*5.5

x =137.5

i believe the correct answer is b.
