A writer wants to hire someone to type the manuscript for his new novel. The speed of Typist A can be modeled by the function W(t) = 170,000 – 65t where the number of words remaining to be typed, W(t) is a function of t, time. The speed of Typist B is modeled by the function W(t) = 170,000 – 50t where the number of words remaining to be typed, W(t) is a function of t, time. Based on this information, which statement is true?

• The entire manuscript is typed 15 words per minute faster by Typist B than Typist A.
• The entire manuscript is typed 15 words per minute slower by Typist B than Typist A.
• The entire manuscript is typed the same number of words per minute by either typist.
• After 100 seconds, the basketball is 2.5 feet in the air.
