toolang dijawab dengan caranya

a) 24 km/jam
= 24 × 1.000/3600
= 6,7 m/detik

b) 75 km/jam
= 75 × 1.000/3600
= 20,8 m/detik

c) 2,4 km/jam
= 2,4 × 1.000/60
= 40 m/mnt

d) 45km/jam
= 45 × 1.000/60
= 750 m/mnt

e) 15 m/dtk
= 15 × (1/1000 ÷ 1/3600)
= 15 × 36/10
= 15 × 18/5
= 54 km/jam

f) 50 m/dtk
= 50 × (1/1000 ÷ 1/3600)
= 50 × 36/10
= 180 km/jam

g) 2 cm/dtk
= 2 × (1/100000 ÷ 1/3600)
= 2 × 36/1000
= 0,072 km/jam

h) 40 cm/dtk
= 40 × (1/100 ÷ 1/60)
= 40 × 6/10
= 24 m/mnt

i) 7 m/dtk
= 7 × 100
= 700 cm/dtk
