Solve the following problem given below:
Problem: You normally drive on the freeway between San Diego and Los Angeles at an average speed of 105km/h, and the trip takes 2 h and 20 min. On a Friday afternoon, however, heavy traffic slows you down and you drive the same distance at an average speed of only 71.0km/h.
Part A- How much longer does the trip take?
I have been stuck on this problem for a long time, please help. Show steps. THANKS!
