Help with the case study

I have a case that I need help with.


 
CASE STUDY 1
John Peterson’s business nearly went under when Massachusetts almost passed the health bill. Peterson’s company produced kettle cooked chips for many of the large grocery stores in the area. After the health bill failed, Peterson’s company flourished. In a few short years, the company had a major plant in Ashland with a warehouse in east Ashland. The problem was getting the finished product to the warehouse. Although John was not good with distances, he was good with times. Ashland is a big city with numerous roads that could be taken from the plant to the warehouse.

➢ The kettle cooked chips plant is located at the corner of North Street and Columbine Street.
➢ High Street also intersects North and Columbine Street at the plant.
➢ Twenty minutes due north of the plant on North Street is I-70, the major east–west highway in Ashland.
➢ North Street intersects I-70 at Exit 135.
➢ It takes five minutes driving east on I-70 to reach Exit 136.
➢ This exit connects I-70 with High Street and 6th Avenue.
➢ Ten minutes east on I-70 is Exit 137. This exit connects I-70 with Rose Street and South Avenue.
➢ From the plant, it takes 20 minutes on High Street, which goes in a northeast direction, to reach West Street.
➢ It takes another 20 minutes on High Street to reach I-70 and Exit 136.
➢ It takes 30 minutes on Columbine Street to reach West Street from the plant. Columbine Street travels east and slightly north.
➢ West Street travels east and west.
➢ From High Street, it takes 15 minutes to get to 6th Avenue on West Street. Columbine Street also comes into this intersection.
➢ From this intersection, it takes an additional 20 minutes on West Street to get to Rose Street, and another 15 minutes to get to South Avenue
➢ From Exit 136 on 6th Avenue, it takes 5 minutes to get to West Street.
➢ Sixth Avenue continues to Rose Street, requiring 25 minutes.
➢ Sixth Avenue then goes directly to the warehouse. From Rose Street, it takes 40 minutes to get to the warehouse on 6th Avenue.
➢ At Exit 137, Rose Street travels southwest. It takes 20 minutes to intersect with West Street, and another 20 minutes to get to 6th Avenue. From Exit 137, South Avenue goes due south. It takes 10 minutes to get to West Street and another 15 minutes to get to the Warehouse.
What do you recommend?
Draw diagram show three possible scenarios and conclude with an explanation.

The case is Homework. What kind of help are you looking for?

I am lost .. need a diagram mapping the plant to all the listed routes.

Two comments on the structure of the problem

The introduction seems highly political

One of the trip legs goes on Interstate I70. from exit 135 to exit 136 in five minutes.
This time seems much too long for a 1 mile interstate segment.
