Step-by-step explanation:
Deisha's build rate = 1 fence per 15 hours = 1/15 fences per hour
Travis's build rate = 1 fence per 12 hours = 1/12 fences per hour
Working together, their combined rate is 1/15 + 1/12 = 3/20 fences per hour
So it takes them 20/3 = 6 2/3 hours per fence
Given that an empty box weighs 2 and 1/4 pounds.
Weight of the fruit is 16 and 2/3 pounds.
Weight of filled box means total weight of box and the fruit.
So we will add both values.
2 and 1/4 pounds+ 16 and 2/3 pounds
= 2 + 1/4 + 16 + 2/3 pounds
= 2 + 16 + 1/4 + 2/3 pounds
= 18 + 1/4 + 2/3 pounds
Hence final answer is 18 and 11/12 pounds.
