First you must calculate the speed of Amy and speed of Bill.
Now calculate the difference between Bill's speed and Amy's speed.
Amy's average speed is not faster. Bill's average speed is faster than Amy's by 6 m/sec.
Hope this helps.

This is due to water pressure
They use sound waves that bounce off walls, and other things back to them to feel where they are going.
If the resistance of the Air is ignored, we can use the theory given by Galileo in which he warned that the thermal velocity of a body in free fall was given by
Where
g = Gravitational acceleration
t = time
As we can see the speed of objects in free fall is indifferent to the position that is launched (as long as the resistance of the air is ignored) or its mass.
Both bodies will end with the same thermal speed.
Answer:
52.4
Explanation:
we ignore 322 and 19 because they are much bigger or smaller in value. we have to find the average of the rest numbers:(52.3+52.5+52.2+52.6)/4=52.4
