During the 1st part of the trip, the train moves at an average speed 65 miles per hour. During the 2nd part of the trip, the train moves an average speed of 40 miles per hour. Let L be the time it takes for the train to travel the 1st part of the trip. Write and simplify and expression in terms of t for the total distance you traveled in the train. Then find the total distance you traveled if the first part of the trip took 4 hours. </SPAN>\n" );
