A child walks 600 metres in 12 minutes and takes 70 steps per minute. What is the average length of one step in centimetres?

Step-by-step solution

1. Convert the distance to centimetres: $600,\text{m}=600\times 100=60000,\text{cm}$.
2. Compute the total number of steps: $70\times 12=840$ steps.
3. Divide the total distance by the total steps: $60000/840=71.4286\text{ cm}$.
4. Round to two decimal places to give $71.43,\text{cm}$ as the average step length.
