Well, it cant be option B because then it wuld be half the time (180 mins.)

It cant be option D becasue then it would be over 360 mins, seeing that it only took 8 mins to type 360

And it cant be option C beacuse it would be too small, if 4 mins is to small then 3 mins is worse

Your answer would be A 5 minutes it's just a little bit above 4 mins(half)

Answer:

A. 5 minutes

Explanation:

We can solve this question using proportions

Let x be the number of minutes needed to type 225 words.

8 minutes = 360 words

x = 225 words

Cross-multiply

360 × x = 225× 8

360 x = 1800

Divide both-side of the equation by 360


(360x)/(360) =
(1800)/(360)

(On the left-hand side of the equation, 360 at the numerator will cancel-out 360 at the denominator, while on the right-hand side of the equation 1800 will be divided by 360)

x= 5 minutes

Therefore, it will take 5 minutes to type 225 words
