Question

Jack can type 70 words in two minutes. How much time will he take to type 350 words with the same speed?

Answer 1

By the given information, we know that Jack type at a rate of 70 words in 2 minutes, 70/2:

`\frac{70\text{ words}}{2\text{ minutes}}=35\frac{\text{words}}{\text{minute}}`

Which simplified gives us a rate of 35 words per minute.

How many minutes is Jack going to take to type 350 words:

`350\text{ words}*\frac{1\text{ minute}}{35\text{ words}}=10\text{ minutes}`
