(a) the number of photocopies in 5 minute.
(b) the time taken to print 1440 pages.​

Answer 1

Answer:

(a) 1 minutes change seconds

1 minute =60seconds

so total sum of second

30+60=90

48photocopies make 90 second

1 minute =60s

5minutes=5×60=300s

48/90=X/300

48×300=90X

14400/90=X

X=160

(b). 48/90=1440/X

48x=129600

X=2,700
