I have a math porblerm?

My car gets 50 miles per gallon. I'm driving on a highway in a straight line for 2 hours at 100 miles per hour. I have an Orange Julius that's pretty delicious, but then I spill it when my grandma calls my cell to get me to pick up some eggs for her. A litter of puppies crosses the road at the 1 hour mark and I stop for 5 minutes to let them go. The car goes 0 to 60 in 8 seconds. How long will it take me to reach my destination, get eggs for grandma and pick up a new smoothie and also why is this guy in front of me driving so slow?
