Question

1. Informe os valores das velocidades em m/s:
a) 72Km/h
b) 144km/h
c) 36km/h
d) 108km/h
2. Informe os valores das velocidades em km/h:
a) 5m/s
b) 15m/s
c) 20m/s
d) 25m/s

Answer 1

1)

$\mathtt{a)}~\mathsf{72km/h\div3,6=20m/s}\\\mathtt{b)}~\mathsf{144km/h\div3,6=90m/s}\\\mathtt{c)}~\mathsf{36km/h\div3,6=10m/s}\\\mathtt{d)}\mathsf{108km/h\div3,6=30m/s}$

$\dotfill$

2)

$\mathtt{a)}~\mathsf{5m/s\cdot3,6=18km/h}\\\mathtt{b)}~\mathsf{15m/s\cdot3,6=54km/h}\\\mathtt{c)}~\mathsf{20m/s\cdot3,6=72km/h}\\\mathtt{d)}\mathsf{25m/s\cdot3,6=90km/h}$
