Question

A refrigeration assembly line travels 3,000 meters from start to finish. It takes 2 days of 8-hour workdays for a single unit to go from start to finish. How far does the line move each minute? Round the answer to two decimal places.

A. 1.25 meters
B. 3.13 meters
C. 6.25 meters
D. 12.50 meters

Answer 1

The answer is B because 2 workdays of 8 hours equals 960 minutes. And a unit can travel 3.13 meters per minute because 3000 divided by 960 is 3.13 

Answer 2

Option B. 3.13 meters

Explanation:

A refrigeration assembly line travels from start to finish = 3,000 meters.

It takes 2 days of 8 hour workdays for a single unit to go from start to finish.

2 days of 8 hour workdays = 8 × 2 = 16 hours

∵ 1 hour = 60 minutes

∴ 16 hours = 60 × 16 = 960 minutes.

Now we will divide total distance to 960 minutes.

The line move each minute =
`(3000)/(960)`

= 3.125 ≈ 3.13 meters/ min.

The line moves 3.13 meters each minute.

Option B. 3.13 meters
