Question

Clark typed 720 words in 18 minutes. How many words can he type in one minute?​

Answer 1

720/18 = 40

He can type 40 words a minute

Answer 2

Clark can type 40 words in one minute

Explanation:

1. Set up a proportion:
   `(720)/(18) = (x)/(1)`
2. Cross multiply, then divide: 720 × 1 = 720, 720 ÷ 18 = 40
3. So, x = 40
