Use dimensional analysis to change 231 mph to kilometers per minute.

Question

 I don't need just the final answer. I also need to know how to do the dimensional analysis part.

Answer 1

231 m/h = 231 miles/hour*/60 min/hr = 3.85 miles/min

 

= 3.85 miles/min*5280 ft/mile = 20328 ft/min

 

= 20328 ft/min* 0.3048 meters/ft = 6196 meters per minute

 

= 6196 m/min * 0.001 km/m = 6.196 km/min
