Answer:
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.
