24 km/jam = (24 x 100) dam / (1 x 60) menit
                  = (2.400 / 60) dam / menit
                  = 40 dam/menit

5.000 meter/jam = (5.000 : 1.000) km/jam
                           = 5 km/jam

120 cm/detik = (120 : 100) m / (1 : 60) menit
                      = (1,2 x 60) m/menit
                      = 72 m/menit

180 km/jam = (180 x 1.000) m / (1 x 60) menit
                    = (180.000 : 60) m/menit
                    = 3.000 m/menit

4) 24 km/jam
= 24 × 100/60
= 40 dam/mnt

5.000 m/ jam
= 5.000 × 1/1.000
= 5 km/jam

120cm /dtk
= 120 × (1/100 ÷ 1/60)
= 120 × (1/100 × 60/1)
= 120 × 60/100
= 72 m/mnt

180 km/jam
= 180 × 1000/ 60
= 3.000 m/mnt
