Step-by-step explanation:
A reflection followed by a translation
It might be helpful to write up the question like this:
300=100%
3=1%
120=
If you do this, you’ll see that the question is really easily solved by just finding the number necessary to multiply 3 with to get 120.
If you understand this, the rest should follow.
1a (you don’t necessarily need to include the 1, so you can just put “a” if you’d like).
The square root of 25 is 5
First you divide 1200 by 25 (1200/25) it comes out to 48.
That means the he types at a rate of 48wpm. So then all you have to do is multiply 48 and 45 and you get 2160 words.
