Answer:
It takes Mark 268 minutes to type 5356 words
Step-by-step explanation:
We can easily solve this using proportion;
let x be the number of minutes that will take Mark to type 5356 words,
20 words = 1 minute
5356 words= x
Cross multiply
20x = 5356
Divide both-side of the equation by 20
20x/20 = 5356/20
(On the left-hand side of the equation 20 at the numerator will cancel-out the 20 at the denominator leaving us with just x, while the right-hand side of the equation 5356 will be divided by 20)
x = 5356/20
x=267.8
x≈268
Therefore, it takes Mark 268 minutes to type 5356 words
This question is based on the concept of division. Therefore, the 268 minutes he would be taken to finish typing his essay.
Given:
He can type 20 words per minute.
We need to determined the time it take Mark to finish typing his essay.
According to the question,
Let x be the number of minutes that he will take to type 5356 words.
It is given that, 20 words = 1 minute.
Thus, 5356 words = x
Now, calculating the time for 5356 words. Then,
⇒ 20x = 5356
Divide both-side of the equation by 20.
We get,
⇒ [tex]\dfrac{20 \, x}{20} = \dfrac{5356}{20} \\\\[/tex]
Now, solve it further.
⇒ [tex]x = \dfrac{5356}{20}[/tex]
⇒ x = 267.8
⇒ x ≈ 268
Therefore, the 268 minutes he would be taken to finish typing his essay.
