Answer: It will take her 15 more hours to finish the book.
Step-by-step explanation:
25% : 5h
50% : 10h
75% : 15h
100% : 20h
It would take 20 hours to complete the book, but because she already read for 5 hours, it would be 15 to finish the book.
Answer:
15 hours
Step-by-step explanation:
The way we can find this is by taking both 25% and 5 and multiplying them by 4. The reason we do this is because 25% x 4 will equal 100% so it will show us how many hours total she needs to read.
5 x 4 = 20
Now we just subtract the amount of hours she has already read for which is 5.
20 - 5 = 15
