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 120 km, but then construction work forces you to slow to 42.0 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?

Hunter is in lab. he clears a spot on his lab bench to start working. he also puts his lab coat and goggles on. he then identifies where all of the safety equipment is. he notices his station is next to the fume hood, which ventilates the chemicals stored there. the noise of the fume hood was bothersome, so hunter turned it off. which could be an error in his set-up? he should not turn off the fume hood.  he should wait to put on his coat until after the directions are given.  he should wait to put on his goggles until after the directions are given.  he should not sit next to the fume hood.
