Question

a recycling plant processes an averge of 1/3 ton of glass each minute. At approximately what rate does the recycling plant process glass. In tons per day? (1 day =24 hours)

Answer 1

Every 3 minutes they make one ton.
there  are 1440 a da24H) s0 1440/3= 480

So they make about 480 tons per 24 hours

Answer 2

Correct answer: B

The first thing to be done is to convert the 2 tons into pounds.

1 pound is equal to 0.0005 tons (US). So, 2 tons divided by 0.0005 will give us the aluminium pounds per week that are processed by the Recycling Centre B.

=4000

Recycling Centre B processes 4000 pounds/week. In order to compare to Recycling Centre A, we need to find the rate in pounds per hour. To do so divide the 4000 pounds by 168 (24×7 = number of hours in a week).

≈23.8

The Recycling Centre B processes about 23.8 pounds/hour whereas the Recycling Centre A processes 100pounds/hour.
