Question

If sarah can type 32 words in 30 seconds how many words can she type it 2.75 minutes

Answer 1

176 words

we require 2.75 minutes in seconds

using 1 minute = 60 seconds then

2.75 = 2.75 × 60 = 165 seconds

Using proportion to solve

divide 32 by 30 to obtain words per second then multiply by 165 to obtain number of words typed in 2.75 minutes.

number of words = 32 ×
`(165)/(30)` = 176
