1. 5/2 jam = 8/3 m >> 15 jam = 16 m >> 1 jam = 16/15 m >> 2 jam = 32/15 m
3. 3/2 jam = 12 km >> 3 jam = 24 km >> 1 jam = 8 km >> 1 x 9/4 jam = 8 x 9/4 km >> 9/4 jam = 18 km >> 9/4 jam = 2 jam 15 menit
4. 1 km = 100000 cm >> 1 cm : 800000 cm = 1cm : 8 km >> 32 km / 8 km = 4
3. 2 jam 15 menit
4. jaraknya itu 4 cm
