Answer 1

A) 15:30

B) 8 km

Explanation:

a) At 15:30, Bethan's journey line intersects the y-axis, indicating her arrival at home from school.

b) Siobhan's journey line starts and ends at 2 km on the x-axis, which represents the distance from her home. Therefore, Siobhan travels a total of 4 km to school and 4 km back, so she travels a total distance of 8 km each day.
