Her husband drives 40 miles per hour and has a 15 minute head start. If Karen (with the briefcase) drives 60 miles per hour and the airport is 45 miles away, will she catch him before he arrives at the airport? : Find out how long it will take to catch him Change 15 min to .25 hrs : t = K's travel time then (t+.25) = hus travel time : When K catches h, they will have traveled the same distance Write a distance equation; dist = speed * time 60t = 40(t+.25) 60t = 40t + 10 60t - 40t = 10 20t = 10 t = t = .5 hr for K to catch h : Find the distance 60*.5 = 30 mi, well before the airport which is 45 mi : Confirm solution by finding the dist h travels 40 *(.5+.25) = 30mi also
