Roger ran 13.2 miles in 1.6 hours. ana ran 10.85 miles in 1.4 hours. who had the faster average speed? how much faster? explain.

Roger, by 0.5mph

Step-by-step explanation:

To work out speed, you need to do distance traveled divided by time.

Roger: 13.2 / 1.6 = 8.25mph

Ana: 10.85 / 1.4 = 7.75mph

Roger has a faster average speed.

8.25 - 7.75 = 0.5

He was faster by 0.5mph

Hey!

Average Speed = Distance / Time

Solve for Roger:

13.2 / 1.6 = 8.25mph.

Solve for Ana:

10.85 / 1.4 = 7.75mph.

Now, we can see that Roger has the fastest average speed.

Subtract:

8.25 - 7.75 = 0.5mph.

Now, we can see that Roger was 0.5mph. faster then Ana.

Hope This Helped! Good Luck!

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
