It takes 2.18 hours for the runners to cross. Runner A is 6 km west of the start of the race when the runners cross. The runners are 0.91 km east of the flagpole when their paths cross. This is 0.91 km east of the flagpole because when they cross, they have each traveled 0.91 km further than the flagpole, which is each in the opposite direction.
