Eduardo Moody · Answer 1

Mr Frost typed 600 words in 12 minutes (50*12)

so to find out how fast it took mrs. grey to type 600 words you just 600:60 (because that's how many words a minute Mrs. grey types)

so the answer would be 10 minutes

Let x = Mrs. Grey's time.

Set up. 12 (50) = x (60) Solve for x. x=10. Check. 12 (50) = 10 (60)
