Try a different time for 5 km

5 km in 1 hour = 1:12/100 m
5 km in 1 hr 5 min = 1:18/100 m
5 km in 1 hr 10 min = 1:24/100 m
5 km in 1 hr 20 min = 1:36/100 m
5 km in 1 hr 30 min = 1:48/100 m
5 km in 1 hr 40 min = 2:00/100 m
5 km in 1 hr 50 min = 2:12/100 m
5 km in 2 hours = 2:24/100 m

Faster: 1 hr 50 min = 2:12/100 m
