nyatakan nilai kelajuan berikut ini dalam km/jam. a 2 m/s. b 5 m/s. c 10 m/s

dari m ke km dibagi 1000
dari s ke jam dibagi 3600
maka

a. 2 m/s = (2/1000)/(1/3600) = (2/1000) x (3600/1) = 7200/1000 = 7,2 km/jam

b. 5 m/s = (5/1000)/(1/3600) = (5/1000) x (3600/1) = 18000/1000 = 18 km/jam

c. 10 m/s = (10/1000)/(1/3600) = (10/1000) x (3600/1) = 36000/1000
                 = 36 km/jam

2 m/s
= (2 × 10^-3)/(1/3600) km/jam
= 2 × 10^-3 × 3600
= 2 × 3,6
= 7,2 km/jam

Cara yg sama
5 m/s = 5 × 3,6 = 18 km/jam
10 m/s = 10 × 3,6 = 36 km/jam
