Question

Miguel typed 270 words in 6 minutes. His paper is 630 words. If he keeps typing at the same rate, in how many more minutes will Miguel finish typing his paper?

A. 8 minutes
B. 14 minutes
C. 16 minutes
D. 22 minutes

Answer 1

630-270 = 360 words remaining

Rate = 270words/6min=45wpm

Time left = 360words/45wpm = 8mins.

Answer 2

270/6, 630/x
you just cross multiply
270x=6*630
x=6*630/270
x=14
