Question

a machine prints 1800 newspapers in 45 minutes . how many will it pint in 4 hrs 30 minutes?​

Answer 1

Answer:

10,800

Step-by-step explanation:

4 hours 30 minutes = 270 minutes

45 minutes → 1,800 papers

1 minute → 1800 ÷ 45 papers

⇒ 1 minute → 40 papers

∴ 270 minutes → 270 × 40

⇒ 270 minutes → 10,800 papers

∴ In 4 hours and 30 minutes, 10,800 papers are printed

Answer 2

Answer:

10,800 newspapers

Step-by-step explanation:

Let is first find that in one minute how much newspapers are printed.

No. of newspaper printed per minute

$= \frac{given \: number \: of \: \: newspapers }{time \: taken \: to \: print \: given \: no \: newspapers} \\ = \frac{1800}{45} \\ = 40newspapers \: per \: minute$

So 40 newspapers are printed in each minute therefore in 4h 30 minutes (i.e.270minutes )

the number of newspapers printed will be

=Newspapers per minute × Time asked

= 40 ×270

=10,800

so 10,800 newspapers will be printed in 4h30min.
