Question 530944
you find the conversion factor.
you set it up like this:
44ft/second and since there are 3600 seconds in an hour (60 minutes x 60 seconds) you times 44ft/1 second x 3600 seconds/ hour 
you can then cross cancel the seconds (as in the words) 
then since its miles per hour you would do 1 mi/5280 ft because thats how many feet are in a mile and you cross cancel the feet

so far this is what you should have:
44ft/1 x 3600/1 hr x 1 mi/5280
then you multiply 44 and 3600 which is 158,400 and you divide that by 5280 which is 30. 

the answer is 30mi/hr
