Question 903128: What would be the answer to this?
A car is traveling at 3.49 km per hour. What is its speed in feet per second?
I started out by finding the conversions to get me to ft. and sec.
1000m=1 km
100 cm=1 m
2.54 cm=1 in
12 in= 1 ft
60 sec= 1 min
60 min= 1 hr

That list looks like all the right information. Use each conversion relationship in the form of a fraction. Keep the unit with the number; you want to arrange the conversion ratios so that the units will cancel and you finish with feet per seconds.



Notice which numbers are part of numerator and which are part of denominator; and note the way the units cancel to yield feet per second.
