Question

You have to type up a 400 word paper. If you can type 25

words in 3 minutes, how long will it take you to type the
paper?

Answer 1

48 minutes

Explanation:

25 words - 3 minutes

400 words - x minutes

Cross multiply

25x = 400 x 3

25x = 1200

Divide both sides by 25

x = 1200/25

x = 48

Answer 2

48 minutes

Explanation:

25=3 400/25=16x3=48
