Nancy leaves the school and drives toward her town at 27 mph. greg leaves the same school 2 hours later and drives the same route at 45 mph. how long will it take greg to pass nancy?
Nancy's rate=27 mph Greg's rate=45 mph t=Greg's time t+2=Nancy's time Since they both traveled same distance then: 27(t+2)=45t 27t+54=45t 18t=54 t=3 hours Greg will pass Nancy after 3 hours
