Question

Converta as Unidades. A) 12 m/s para km/h​

Answer 1

1 km = 1000 m

1 h = 60 s x 60 x = 3600 s

1 km/h --------------- 1000 m/3600 s

x km/h --------------- 12 m/s

(1000/3600)x = 12

1000x = 12.3600

1000x = 43200

x = 43200/1000

x = 43,2 km/h

Answer 2

Basta multiplicar por 3,6

a) 12m/s x 3,6 = 43,2km/h
