Which model would you use to change 12 minutes to seconds? 12 min x 60 sec/ 1 min Which model would you use to convert 35 miles per hour to feet per second? 35 mi/hr x 5280ft / 1 mile x 1hour/ 3600 sec

The answer is E.
You would need 35 miles over one hour times how many feet are in a mile 5280 over how many seconds are in an hour 3600.
35mi 5280ft
---- X --------
1hr 3600sec

Start by ignoring everything but the units. Which answer cancels out all units except ft/sec?
Now, are any of the conversions in there incorrect? Is it 1 hour = 360 seconds, or 1 hour = 3600 seconds? And then you're done!

It's D!!! (35mi/hr)*(5280ft/mi)*(1hr/3600sec)

35 mi/hr = 35mi/hr (5280ft/mi)(1/3600 hr/sec) = 51.3 ft/sec
