1 markJalina left her home at 10 00 to cycle to a park.
On her way to the park, she stopped at a friend’s house and then continued her journey to the park.
Here is the distance-time graph for her journey to the park.
On her journey to the park, did Jalina cycle at a faster speed before or after she stopped at her friend’s house?
Give a reason for your answer.
2 marksJalina stayed at the park for 45 minutes.
She then cycled, without stopping, at a constant speed of 16 km/h from the park back to her home.
Show all this information on the distance-time graph.
3 marksWork 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.
