Question

Sally is training for a marathon. She goes for a run every Tuesday and

Last week, on Tuesday she ran 2.4 km in 18 minutes. On Friday she ran 1.8 km in 12 minutes.
A.Work out the speed Sally ran each evening, in kilometres per minute,
B.On which evening did Sally run faster?

Answer 1

Speed = distance / time

Tuesday: speed = 2.4km / 18 minutes = 0.13 km per minute

Friday: speed = 1.8 km / 12 minutes = 0.15 km per minute

0.15 is larger than 0.13 so she ran faster on Friday.
