You drive from Hillsboro to Sault Ste. Marie Canada, $585$ miles on $27\mathrm{.}45$ gallons of gas. The north shore route to Duluth, MN$,$ is $1002km$ on $98\mathrm{.}2$ Liters of gas.

FOR THIS PROBLEM ONLY GIVE ALL ANSWERS ROUNDED TO THE APPROPERATE SIGNIFICANT FIGURES

a$)$ What was your overall MPG$.$

b$)$ Which leg of the trip was more fuel efficient, Hillsboro to Sault Ste. Marie OR Sault Ste. Marie to Duluth, MN

c$)$ During you drive you are slowed by a logging truck on a road with one lane in each direction. You estimate its length to be $20\mathrm{.}0m.$ You determine that it is traveling at $45\mathrm{.}0mph.$ If the speed limit is $90\mathrm{.}0kmph,$ assuming that you are starting $40\mathrm{.}0m$ behind the truck when you start the pass, that you will merge back into your lane when you have a minimum distance of $20\mathrm{.}0m$ in front of the truck, and you will not break the speed limit$,$

$($I$)$ how much time will it take you to pass the truck

$($II$)$ how log of a stretch of road with clear opposing traffic will you need to complete the pass
