Question

a printing press will print 6,000 copies in 20 minutes. A second press can print 15000 copies in 60 minutes. How many more copy per minutes will the faster press print more than the slower press?

Answer 1

6000/20 = 300 pgs per minute
15,000/60 = 250 pgs per minute

the faster press will print 50 more pgs per minute then the slower press

Answer 2

Answer: 50 copies per minute.

Step-by-step explanation:

Given: A first printing press will print 6,000 copies in 20 minutes.

Then the rate of printing per minute by first press is given by :-

$\frac{6,000}{20}=300\text{per minute}$

Also, A second press can print 15,000 copies in 60 minutes.

Then the rate of printing per minute by second press is given by :-

$\frac{15,000}{60}=250\text{per minute}$

Clearly, 300> 250

i.e The first press is faster than the second press.

Difference=$300-250=50$

Hence, the faster press will print 50 copies per minute more than the slower press.
