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
