Question

A factory has two types of machines.

Answer 1

Answer:

7875 parts

Step-by-step explanation:

#Find the number of parts cut by the machine per hour:

$=105\times \frac{60\ min}{3\ min}\\\\=2100\ parts$

#Find the number of parts per machine per hour:

$p/m/h=\frac{2100}{6}\\\\=350\ parts$

#Given that only 5 machines are now working for 4.5 hrs, we calculate the total parts as:

$Parts=p/m/h\times\times \ number \ of \ machines \times time\\\\=350\times 5\times 4.5\\\\=7875\ parts$

Hence, the total parts cut by 5 machines is 7875 parts
