(a) At Smith's Bike Rentals, it costs $16 to rent a bike for 3 hours. How many hours of bike use does a customer get per dollar?

(b) A color printer prints 9 pages in 3 minutes. How many pages does it print per minute?

If necessary, round your answers to the nearest hundredth.

Respuesta :

a. The unknown is how many hours is to one dollar.
The given is $16 is to 3 hours
If $16=3 hrs(1 hr=60 mins so 3*60=180 mins)
   $1=?
$1/$16*180 mins=11 mins(rounded to nearest ones)
Therefore about 11 mins or (11.25/60=0.1875hrs) is to 1 dollar
