3.3 Graphs question 1

[Maximum number: 3]

Jalina left her home at 1000 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.

Figure for Question 3.3 Graphs question 1 — Edexcel IGCSE Math A Foundation

Question (a)

(a)

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.

Jalina stayed at the park for 45 minutes.
She then cycled, without stopping, at a constant speed of 16 km/h16 \mathrm{~km} / \mathrm{h} from the park back to her home.

Work out the value of P when g=7 and h=-4
