will Eugene type?

C.

B.

D. 1.200

Answer 1

Answer: B. 450

Explanation:

Eugene can type 55 words per minute, so in 30 minutes he will type 55 * 30 = 1650 words.

Allen can type 80 words in 2 minutes, so in 30 minutes he will type 80 * 15 = 1200 words.

To find out how many more words Eugene will type than Allen, we subtract Allen's total from Eugene's total:

1650 - 1200 = 450 words

So, Eugene will type 450 more words than Allen in 30 minutes. Therefore the answer is B. 450

Answer 2

B. 450

Explanation:

We can find how many words each person types by multiplying how fast they type by how long they get to type (30 minutes).

Eugene:

`(55 \: words)/(1 \: minute) * 30 \: minutes \: = 1650 \: words`

Allen:

`(80 \: words)/(2 \: minutes) * 30 \: minutes \: = 1200 \: words`

we can find how many more words Eugene types using subtraction

`1650 - 1200 = 450`

Eugene types 450 more words
