Question 735791: Please help me with this problem:
"Tom and Ray were cruising the Massachusetts Turnpike in Tom's '79 Fiat Spyder, enjoying the beautiful fall colors for which New England is so justly famed. Ray noted that at 60mph the tachometer read 3000rpm and wondered how many feet the car traveled in the time the engine made one revolution. What was his answer?"
- Thank you for your time.

Convert miles/hr to feet/min
( miles / hr ) x ( ft / mi ) x ( hrs / min ) = ft / min
+60%2A5280%2A%281%2F60%29+=+5280+ ft/min
Set up a proportion:
( ft / min ) / ( revs / min ) = ft / rev
ft / rev = ft / rev
+5280+%2F+3000+=+1+%2F+x+
+5280x+=+3000+
+x+=+3000%2F5280+
+x+=+.5682+
The car travels .5682 ft in 1 engine rpm at 60 mi/hr
