What is this distance in kilometres (km)?

2. Vin completes laps of a cycle track with the times shown in the table. Each lap is 250 metres (m).

What is the range of the lap times?

Task B

1. Sam cycles for 2 hours and 30 minutes each week. She cycles on 5 days of the week and for the same length of time each day.

How many minutes does she cycle each day?

2. Sam uses 720 calories in 60 minutes of cycling. She drinks a can of lemonade which contains 168 calories.

3. Jay cycles and goes to the gym. Each week 2/3 of his exercise is cycling and the rest is in the gym.

What percentage of his exercise is in the gym?

Task C

‘Cycling is one of the easiest ways to fit exercise into your daily routine because it's also a form of transport. It saves you money, gets you fit and is good for the environment.’
