Answer 2

It will take 20 minutes to type 350 words.

In 6 minutes, 105 words can be typed.

Explanation:

To find the time taken to type 350 words, divide 4 by 70 and then multiply it by 350.

`\sf \text{Time taken to type 1 word = $(4)/(70) $}\\\\\text{Time taken to type 350 words = $(4)/(70)*350$}`

= 20 minutes

To find the number of words to be typed in 6 minutes, first find how many he can type in 1 minute.

Number of words typed in 4 minutes = 70 words

`\sf \text{Number of word typed in 1 minute = $(70)/(4)$}\\\\\text{Number of word typed in 6 minute = $(70)/(4)*6$}`

= 105 words
