The HW is online, which is alright but our class is really short and don't have much time with the instructor, so I was wondering if any of you could help me wit this problem.
You are to drive to an interview in another town, at a distance of 300 km on an expressway. The interview is at 11:15 a.m. You plan to drive at 100 km/h, so you leave at 8:00 a.m. to allow some extra time. You drive at that speed for the first 100 km, but then construction work forces you to slow to 41.0 km/h for 41.0 km. What would be the least speed (in km/h) needed for the rest of the trip to arrive in time for the interview?
