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.
AMP Parsing Error of [3.49(km/hour)*1000(m/km)*100(cm/m)*(1/2.54)(inch/cm)*(1/12)(feet/inch)*(1/60)(hour/min)*(1/60)(min/sec)]: Invalid function ')': opening bracket expected at /home/ichudov/project_locations/algebra.com/templates/Algebra/Expression.pm line 70.
.
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.
