Ag obrachadh a-mach luaths le fios air an astar agus an 霉ine
Feuch na h-eisimpleirean seo:
Question
Tha Ailean a' siubhal \(100\,km\) ann an \(\text{5 uairean a th矛de}\).
Obraich a-mach an luaths cuibheasach aige ann an \(km/u\).
\(\text{Luaths} = \frac{{\text{Astar}}}{{\text{脵ine}}}\)
\(\text{Luaths} = \frac{{100}}{{5}}\)
\({Luaths = 20\,km/u}\)
B' e \(20\,km/u\) luaths cuibheasach Ailean.
Question
Obraich a-mach luaths tr猫ana a tha a' siubhal \(243\,km\) ann an \(\text{2 uair 15 mionaidean}\).
\(\text{Luaths} = \frac{{\text{Astar}}}{{\text{脵ine}}}\)
\({脵ine = 2 uair \,15 mionaidean}\)
\({15 mionaidean = 0.25 u}\)
\(\text{Luaths} = \frac{{243}}{{2.25}}\)
\({Luaths = 108\,km/u}\)
Tha an tr猫an a' siubhal aig \(108\,km/u\).
