3.48 lb/h

Explanation:

Answer 2

Option A - 3.48 lb/hours

The trash produced per one hour is 3.48 lb/hours

Solution:

Given that On average, a factory produces 585 lb of trash a week

To find: Amount of pounds of trash produced per hour

We know that one week has 7 days. Also one day has 24 hours

1 day = 24 hours

1 week = 7 days = 7 x 24 = 168 hours

So we can say 585 lb of trash has produced in 168 hours

So trash produced in one hour can be calculated by dividing 585 lb by 168 hours

`\text {trash produced in 1 hour }=\frac{585 \text{lb}}{168 \text { hours }}=3.48 \mathrm{lb} / \mathrm{hours}`

So the trash produced per one hour is 3.48 lb/hours
