Question

Lula is reading a book for school that is 175 pages long. So far, she has read 50 pages. She can read 25 pages per hour. How many hours will it take her to finish the remainder of the book? Which answer choice best represents the unknown quantity in this problem ?

Answer 1

Answer: 5 hours

Step-by-step explanation:

She has already read 50 pages so we need to deduct that to calculate the answer:

= 175 - 50

= 125 pages left

She can read at a speed of 25 pages per hour. The number of hours it would take to read the remainder of the book would therefore be:

= 125 pages / 25 pages per hour

= 5 hours
