Question

Question: During which section was the person moving at the highest speed? What was their speed? Defend your answer

Answer 1

the person was moving the highest at C

since speed=gradient in distance time graphs so if you find each gradient c will be the highest being 30m/h while point A was 7.5m/h, b was stationery and point d was -20m/h, negative means it's decelerating. you could also guess that C has the highest speed since its the steepest line out of them all.

Answer 2

C

Explanation:

Speed is distance/time. We can solve for the highest speed by looking at each spot on the graph.

In a, the highest speed is 7/1, or 7. In b, it's 30/4, or 7.5. In c, it's 60/7, or about 8.57. In D, it's about the same, but since it's decreasing drastically, it will go to C.
