Assume that after sitting at McDonald's for 1 hour, I got back on the highway and again made good time averaging 78 mph for the next 1.5 hours followed by 45 minutes averaging 35 mph before stopping for the night.  Create the piecewise function that models the complete road trip for that day. Explain the process/reasoning you used to create the rules and conditions that make up these last 3 pieces of the function.
