To convert from pounds per minute to ounces per hour, you can follow these steps:
-
Convert pounds to ounces:
Since there are 16 ounces in a pound: \[ 21 \text{ pounds} = 21 \times 16 \text{ ounces} = 336 \text{ ounces} \] -
Convert minutes to hours:
Since there are 60 minutes in an hour: \[ 1 \text{ minute} = \frac{1}{60} \text{ hours} \] Thus, for 21 pounds per minute: \[ 21 \text{ pounds per minute} = 336 \text{ ounces per minute} \times 60 \text{ minutes per hour} = 336 \times 60 \text{ ounces per hour} \] -
Calculate the final value:
\[ 336 \times 60 = 20160 \text{ ounces per hour} \]
Therefore: \[ 21 \text{ pounds per minute} = 20160 \text{ ounces per hour} \]
