Calculations involving distance, speed and time can be worked out using formulae. When doing these calculations, the units used should be consistent.

Iain walked from his parents' farm into town at a steady speed of \(5km/h\).
The journey took \(3\,hours\). How far did Iain walk?
\(Distance = Speed \times Time\)
\(Distance = 5 \times 3\)
\(Distance = 15km\)
Shona cycles at an average speed of \(8km/h\).
How far has she travelled if she cycles for \(4\,hours\)?
\(Distance = 8 \times 4\)
\(Distance = 32km\)
Shona has travelled \(32km\).
