Luis: 50 words per minute x 12 minutes = 600 words
Miss: 60 words per minute x _____minutes
Miss = Luis
60x = 600
[tex]\frac{60}{60}[/tex]x = [tex]\frac{600}{60}[/tex]
x = 10
Answer: 10 minutes
If the first writer types 50 words per minute for 12 minutes, we tipes
[tex] 50 \dfrac{\text{words}}{\text{minute}} \times 12 \text{ minutes} = 50\times 12 \text{ words} = 600 \text{ words} [/tex]
The second writer types the same amount of words at 60 words per minute, so it will take her
[tex] \dfrac{600 \text{ words}}{60\dfrac{\text{words}}{\text{minute}}} = 10\text{ minutes} [/tex]
