Cycling timing challenge
Two cycling-mad schoolchildren are taken on a tour of the National Cycling Centre in Manchester. They meet world individual pursuit champion Sarah Storey and are set a maths challenge related to cycling.
The challenge is to find out how consistently Sarah’s teammate can keep her speed throughout an 8-lap training session. They must time how quickly she completes each lap, then work out the difference between the fastest and the slowest lap. Having completed the challenge, the two children are presented with medals by Sarah.
