PLUS Malliday, Fundamentals of Physics, 11e PHYSICS I&II (PHY 211/213/225) RCES Chapter 02, Problem 011 You are to drive to an interview in another town, at a distance of 310 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 120 km, but then construction work forces you to slow to 41.0 km/h for 43.0 km. What would be the least speed needed for the rest of the trip to arrive in time for the interview? Number Units the tolerance is +/-2% 7 20,
