0.3

Explanation:

Divide the number of pages by the time

R = D/T

R the rate is the number of pages per min.

D = The distance is number of pages = 30

T = the Time = 9 so

# R = 30/9# This can be factored

# R = 10 xx 3/ (3 xx 3 )# This leaves

# R = 10/3# or

# R = 9/3 + 1/3 # so

# R = 3 + 1/3# pages/min

#R=3.33# pages/min #-># #3.33# pages printed in #1# minute

To find out time take to print #1# page->

#1/3.33 # min/page

#(color(red)(0.3)cancel(1))/(color(red)(1)cancel(3.33))# min/page

#0.3/1# min per page.

Therefore it takes #0.3# minutes for #1# page to print.

The printer takes #0.3# minutes to print one page

Explanation:

The data given to us in the question says that the printer can print #30# pages in #9# minutes.

#(9 min)/(30"pages")# #-># #9# minutes for every #30# pages.

#(color(red)3cancel9 min)/(color(red)(10)cancel(30)"pages")#

#(3 min)/(10 "pages")# #-># #3# minutes for every #10# pages.

#(color(red)(0.3)cancel(3) min)/(color(red)(1)cancel(10)"pages")#

#(0.3 min)/(1"page")# #-># #0.3# minutes for #1# page.

#18 seconds# per page

Explanation:

#30 # pages= 9 minutes

#1# page#=1/cancel30^10xxcancel9^3/1#

#=3/10# minutes

#3/cancel10^1xxcancel60^6/1=18 seconds# per page

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

check:. #18xx30=540 seconds#

#cancel540^9/cancel60^1=9# minutes
