D

Step-by-step explanation:

Let's look at each option:

A. Distance =600 ✓

This is because the graph is a distance- time graph. To find the distance between her house and the post office, look at the y value of the point at the end of her journey. In this case, at t=24 mins, the y -value is 600 and thus the statement is correct.

B. ✓ correct

First 9 mins is from t=0 to t=9. Speed can be found by taking the gradient of the line of a distance- time graph.

Gradient can be found by taking rise/ run, which is also the difference in the y- coordinates divided by the difference in the x -coordinates.

Thus, the speed in the first 9 minutes is indeed 35m/min.

C. ✓correct

Since distance remained at 315m from t=9 to t=13mins, she stopped for that period of time.

Time stopped

= 13 -9

= 4 minutes

D. Incorrect

Average speed= total distance/ total time

Total distance= 600m

Total time= 24 mins

Thus, average speed

= 600 ÷24

= 25m/min

b. qualitative data uses, words while quantitative data uses numbers
