Question

casey types at a constant speed, as shown in the following table.
words typed 1 2 7 12
seconds 5 10 35 60
what does 5 mean in this situation?
choose 1 answer:
a casey types 5 words per second.
b casey types 5 words per minute.
c casey takes 5 seconds to type a word.

Explanation:

Looking at the table, when 1 word is typed, the time taken is 5 seconds. This implies that for each single word Casey types, it takes 5 seconds. Option A is incorrect because if Casey typed 5 words per second, for 1 word the time would be $\frac{1}{5}$ seconds. Option B is incorrect as the table is in seconds and 1 minute = 60 seconds, and the relationship shown is per - word per - second.

Answer:

C. Casey takes 5 seconds to type a word.
