Find an equation for the linear model of the situation below and use it to make a prediction. A train is traveling north at a constant rate. At 3:00 P.M. it is 55 miles north of a city. At 4:15 P.M. it is 80 miles north of the city. If d represents the distance in miles, and t represents the time in hours, how many miles north of the city will the train be at 5:45 P.M.?

„h d = 64t + 55; d = 231 miles

„h d = 80t + 55; d = 255 miles

„h d = 64t + 55; d = 96 miles

„h d = 100t + 55; d = 285 miles

I know the answer is the first choice but I don't understand how to set the problem up.
