Joe is walking at 3 kilometers per hour. Since they meet in 5 hours and Jill walks at 2.5 kilometers per hour, Jill covers 12.5 kilometers (2.5 km/h * 5 h). The total distance is 27.5 kilometers, so Joe covers the remaining 15 kilometers in 5 hours, which means he walks at 3 kilometers per hour (15 km / 5 h).
