A. Let's define t as the time it takes Jerry to type W amount of words. Then, we can use the formula:
W = 71t
B. To find out how long it would take Jerry to type 2556 words, we can substitute W with 2556 and solve for t:
2556 = 71t
t = 2556/71
t ≈ 35.99 minutes (rounded to the nearest hundredth)
So, it would take Jerry approximately 35.99 minutes to type 2556 words.
C. If Jerry typed for 20 minutes, we can use the same formula to find out how many words he typed:
W = 71t
W = 71(20)
W = 1420
Therefore, Jerry typed 1420 words in 20 minutes.
Jerry types 71 words per minute.
