Answer:
He can type 256 words in 4 minutes
Step-by-step explanation:
2 minutes 30 seconds is 2.5 minutes
The rate is the number of words divided by the time
160 words / 2.5 minutes =64 words per minute
We need to find how many words in 4 minutes
Take the rate time the time
64*4 =256
256
2 minutes and thirty is equal to 2.5 minutes.
You divide 160 by 2.5 to find out how many words per minute he can type. You then multiply that number by four because of the four minutes. This results in 256 words in 4 minutes.
I think it would be 7 and 8. 7 squared is 49, and 8 squared is 64. The closest number is 7 tho
19/9 i think
It is linear
If your graph all the points you can see they would be linear
(the equation for the line would be y=3x+2 btw if you need that)
