8.3 Calculation of Speed

Learning Goals

• Level 1: Identify which speed is faster or slower

• Level 2: Given 2 out of the 3 factors, calculate distance, time or speed

Multiple Choice

Tom ran for 2 hours while Sam ran for 3 hours.

Is it fair to say that Tom ran faster?

• Fair

• Unfair

• Cannot conclude

Tom can run 1km in 2 hours.

Sam can run 10km in 3 hours

We need to calculate speed to tell us who ran faster when we consider their distance travelled per unit time (per second, per minute, per hour)
