<PRE><B>Question 96544</B>
At Indianapolis Motor Speedway, one lap is 2.5 miles in length. the 
average speed of an Indy racing car is 190 miles per hour.

Find the length of one lap in yards. ( show work )
One mile is 1760 yards
One lap = 2.5*1760 = 4400 yards
-------------------------------
and then it says:
How many seconds would it take to 
complete one lap.
[2.5 miles]/[190 miles/hour] 
= [2.5/190] hours
= [2.5/190}(hours)(3600 seconds/1 hour)

= [2.5*3600/190] seconds
= 47.368 seconds
