Answer: 215 seconds
Step-by-step explanation:
This is a ratio problem so you can set up the ratio like this:
120 words : 100 second.
If you divide both sides of the ratio by 120 you get:
1 word: 0.8333 seconds
Multiply both sides of the ratio by 258 and you get:
258 words: 215 seconds.
Therefore typing 258 will take them 215 seconds.
This should be the equation:
n + 4/3n + 5/3n = 90
It is a prime because the only other factor of 6w^3-13 is 1.
