ludmilkaskok [199]

The recycling plant processes 480 tons of glass per day.

Step-by-step explanation:

Quantity of glass recycled each minute = $\frac{1}{3}\ tons$

We know that;

1 hour = 60 minutes

Therefore;

Quantity of glass recycled in one hour = $\frac{1}{3}*60=20\ tons$

1 day = 24 hours

Quantity of glass recycled in 24 hours = 24*20 = 480 tons

The recycling plant processes 480 tons of glass per day.
