Your boss, the chief engineer, tells you that, for scheduling purposes, it would be very helpful to know how long a single round trip would take. This is purely transportation time; it does not include time loading, unloading, waiting, etc. - Assume no stops - Ignore acceleration - Ignore the time that the truck spends in the "blue area" (construction zone) or "grey area" (temporary access road). This means that you include only the parts of each truck's route that are black or red in the diagram. - The speed limit on the freeway is 60 mph (1 mile per minute). The speed limit on the cloverleaf ramps is 30 mph (1/2 mile per minute). Assume that the trucks travel at the speed limit. - Assume that there are no differences between the speed of an empty truck and a loaded one. What is the average time of a round trip, in minutes, to the nearest minute? 11 The temporary access road enters the freeway on the westbound side at the 101 mile marker. After they deliver their load, the empty trucks can drive down the westbound side until they exit the freeway at the temporary access road. The charge for an empty truck is $1 per mile on the freeway. There is no charge for the distance they travel on the temporary access road. What is the charge per empty truck to travel the distance from the "Road to be repaired" to the "Temporary access road", for one trip
