<PRE><B>Question 547045</B>
a cheetah was timed running 200 yards in 6 seconds.  What was its average speed in miles per hour?    

you must first do the conversion from yards/second to miles/hour.
Then your problem is solved.

1 yard = 3 feet
600 yards=1800feet

1800 feet in 6 seconds
so in 1 second the cheetah runs
1800/6 = 300 feet /second
....
convert 300 feet/second to miles /hour
1 mile = 5280 feet
1 second = 1/3600 hour  ( 3600 seconds ,ake an hour)

300 feet = 300/5280 miles
1 second = 1/3600 hour

{{{(300/5280)/((1/3600))}}}

{{{(300/5280)*( 3600/1)}}}



=204.5 mph</PRE>
