Ответ:
A. 5 minutes
Step-by-step 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
(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
