Question

What is 3.2 x 10^-4 m/h in centimeters per second?

a) 8.889 × 10^−6 cm/s
b) 8.889 × 10^−5 cm/s
c) 1.152 × 10^−5 cm/s
d) 1.152 × 10^−7 cm/s

not only do I need answers I need to know how A.S.A.P please

Answer 1

`1m=100cm\\h=3600s\\\\3.2*10^(-4)\ m/h=3.2*10^(-4)*(100)/(3600)\ cm/s\\\\=3.2*10^(-4)*(1)/(36)\ m/s=(3.2)/(36)*10^(-4)\ m/s\\\\=0.888...*10^(-4)\ m/s=\boxed{8.889*10^(-5)\ m/s}\\\\Answer:\boxed{b)}`
