When the new exit is built the distance from the exit for Midtown to the exit for Freestone will be miles.

Respuesta :

Refer to the diagram shown below.

The new exit (Freestone) will be midway between Roseville and Freetown.
The distance between Roseville and Freetown is 55 - 33 = 22 miles.
Therefore
a = 22/2 = 11 miles.

The distance from the rest stop to the new exit (Freestone) is
 33 + a = 44 miles.

The distance between the new exit (Freestone) to the exit for Midtown will be
44 - 17 = 27 miles.

Answer:
When the new exit is built, the distance from the exit for Midtown to the exit for Freestone (the new exit) will be 27 miles.
