Favorite Answer
1. First, how many 30 words are there in 213 words? Itβs 213/30 = 7.1
2. Next, how many minutes, Bob can write 213 words. It is 7.1 X 5 = 35.5 minutes
words/minutes====30/5=======213/x
_30_ = _213_
_5__ __x___
then cross multiply
30X = 1065
then divide both sides by thirty
X = 35.5
The answer is 35.5 minutes
30/5 = 213/x
multiply each side by 5
30 = 1065/x
multiply each side by x
30x = 1065
divide each side by 30
x = 35.5 minutes
30 words 213 words
βββββ = βββββ
5 minutes x
NOW, cross multiply and get
30x = 1065
**REMEMBER: 30 times X = 30x; 213 x 5 = 1065
NEXT, DIVIDE BOTH SIDES by 30 to get βxβ by itself
30x = 1065
ββββββ
30 30
x = 35.5 WPM
