Answer:
45%
Step-by-step explanation:
Given
Number of fiction books = 110
Number of non fiction books = 90
Total number of books = 110 + 90 = 200
% of non fiction books
= number of non fiction books divided by the total number of books multiplied by 100%
That’s
90/200 x 100%
0.45 x 100%

Answer:
9 hours, 20 minutes
Step-by-step explanation:
When two ferries work together, they transport a day's cargo in 7 hours
The speed proportion or ratio of larger ferry to smaller ferry is given as 3 : 1
The sum of the ratio = 4 (3 + 1)
This means that it will take the smaller ferry = 7 x 4 hours to work alone = 28 hours, since the larger ferry is faster by 3.
Therefore, when larger ferry works alone, it will take it (7 x 4)/3 = 9.33 hours.
9.33 hours = 9 hours, 20 minutes.
