Let x = Mrs. Grey's time.
Set up. 12(50)= x(60)Solve for x. x=10.Check. 12(50) = 10(60)


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
