Answer:
A
Step-by-step explanation:
She can type 3.75 words per second.
There are 60 seconds in a minute
Therefore she can type 3.75 * 60 = 225 words per minute.
If 1 page contains 675 words, it will take 675 // 225 words /min = 3 minutes
Therefore 25 pages will take 75 minutes (3 * 25 = 75)
75 minutes = 1 hour with 15 minutes left over.
