Answer:
B
Step-by-step explanation:
The given graphs are distance-time graphs, where:
- Time is on the x-axis.
- Distance is on the y-axis.
As Amy walks from her tent to a hilltop in 3 hours, the first part of the graph should be a straight line with a positive gradient, where the x-values of its endpoints are:
Therefore, we can immediately discount answer options A and D as they suggest that this part of Amy's journey takes only 2 hours.
Amy stops and has a picnic at the top of the hilltop for 5 hours. Therefore, her distance from the tent during this time does not change as she is not moving. This will be represented on the graph by a horizontal line that has endpoints at:
Therefore, the graph that displays the given parameters is graph B.
