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.

Distance-time graph, distance from home 0 to 25 km against time 10 00 to 15 00; a line from (10 00, 0) to (11 00, 15), horizontal to (11 15, 15), then a line to (12 00, 24)
(a) On her journey to the park, did Jalina cycle at a faster speed before or after she stopped at her friend’s house?
