The old photocopier can make x manuals in an hour. The new photocopier can make 4x. Combined, they made 5x manuals in an hour.
In one hour they can make 1/28 of the manuals.
1/(28*5)=1/140 is the rate.
The new photocopier can make all the manuals in 4/140 or 35 hours.
The old one can make them in 140 hours.
Answer:
1.125 pages per minute
Step-by-step explanation:
Mika read a 405 page book in 6 hours.
6 hours is equivalent to
6 × 60 minutes = 360 minutes
Number of pages read per minute = 405/360
= 9/8 = 1.125 pages
Mika read 1.125 pages per minute.
The measure will be 180° ± n×360° for some integer n.
For n = -1, the first choice is obtained: -180°
