if a truck mounted crane travels 625feet in 10 seconds, how fast is it traveling in miles per hour

Question

 have to show all work and how you convert

Answer 1

Hi Mitch,

 

We'll step through each conversion to get our answer:

 

    1.  (625 ft / 10 sec)(60 sec / min) =

         (625)(60)/(10) = 3,750 ft / min

 

    2.  (3,750 ft / min)(60 min / hr) =

         (3,750)(60) = 225,000 ft / hr

 

    3.  (225,000 ft / hr)(1 mi / 5,280 ft) =

         (225,000)/(5,280) = 42.61 mph

 

The first two conversions were time unit conversions to go from seconds to per minute and then to per hour. The last conversion was a distance unit conversion to go from feet to miles.

 

Thanks for submitting this problem and glad to help.

 

God bless, Jordan.
