Question

During which interval was the bicyclist speed the greatest? I am not sure about my answer.

Answer 1

you are correct because the elapsed time was the shortest
hope this helps!

Answer 2

ANSWER

The correct answer is A



Step-by-step explanation

The slope between each interval tells us the speed.

The greatest slope is where the speed is greatest.


For the first hour to the second hour,


`slope = (34 - 12)/(2 - 1)`


`slope = (22)/(1) = 22`


For the second hour to the fourth hour,


`slope = (70 - 34)/(4 - 2)`



`slope = (36)/(2) = 18`



For the fourth hour to the sixth hour,


`slope = (104 - 70)/(6 - 4)`


`slope = (34)/( 2) = 17`

For the sixth hour to the eighth hour,


`slope = (146 - 104)/(8 - 6)`



`slope = (42)/(2) = 21`

Therefore the bicyclist's speed was greatest during the first hour to the second hour.
