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.

Step-by-step explanation:
Answer:
Step-by-step explanation:
Since there are nine 2s being multiplied by each other, we can represent this as .
24. 8x3=24
12x2=24
It would be 6/24 (3/12) and 9/24 (3/8)
