Given the statement:
Joan ran 200 yards in 40 seconds, Bill ran 800 yards in 140 seconds.
Determine who ran fast.
Solution:
In order to determine who ran faster, we simply need to take the velocity of each runner. This can be done by dividing the distance with the time.
v = d/t
Joan's velocity:
v = 200 yards / 40 seconds
v = 5 yards/sec
Bill's velocity:
v = 800 yards/140 seconds
v = 5.71 yards/sec
Final answer:
Bill is faster than Joan.
