Figure for Question 4.4.F Average speed, distance and time question 1 — Edexcel IGCSE Math A Foundation

Work out Jalina's average cycling speed, in kilometres per hour, for the complete journey to the park and back.
Do not include the times when she was not cycling in your calculation.
Give your answer correct to 1 decimal place.
