Jake starts at 12.00 and covers 6 km/h Paul starts at 1.30 and covers 8 km/h Relative speed between Jake & paul is 2 kmph, where Paul stating Jake is 9 km ahead of Paul. From 13.30 hours paul takes 4.30 hrs to meet Jake. Again he needs 1.30 hrs to lead Jake by 3 km Relative speed. Totally he takes 6 hrs. so 13.30+6 = 19.30 hrs.
