A machine prints 1500 newspapers in 45 minutes . How many will it print in 2 hours.
Given: A machine prints 1500 newspapers in 45 minutes.
To find: Here we have to find that how many newspapers machine will print in 2 hours.
Solution:
We know that;
2 hours = 2 $\times$ 60 minutes = 120 minutes
Now,
Number of newspapers machine prints in 45 minutes = 1500
So,
Number of newspapers machine prints in 1 minute = $\frac{1500}{45}$
Therefore,
Number of newspapers machine prints in 120 minutes = $\frac{1500}{45} \ \times \ 120$
Number of newspapers machine prints in 120 minutes = 4000
So, machine will print 4000 newspapers in 2 hours.
