To convert pints to cups, you can use the conversion factor that 1 pint is equal to 2 cups.
Given:
\[ 487 \text{ pints/second} = 487 \text{ pints/second} \times 2 \text{ cups/pint} \]
Now, perform the calculation:
\[ 487 \times 2 = 974 \text{ cups/second} \]
So, the equivalent rate is:
\[ 487 \text{ pints/second} = 974 \text{ cups/second} \]
