You are to drive to ah Interview in another town, at a distance km on an expressway. The inter plan to drIve 100 km/h, so you leave at some extra time. You drive at that speed for the first 100 km, but then construction work forces you to slow to 45 km/h for 40 km. What would be the least speed needed for the rest of the trip to arrive in time for the interview?
