To determine how long it will take to run a 52 mL piggyback at a rate of 80 mL per hour, we can use the formula:
Time = Amount / Rate
Given:
Amount = 52 mL
Rate = 80 mL/hour
Substituting these values into the formula:
Time = 52 mL / 80 mL/hour
To simplify, we can divide the numerator and denominator by 4:
Time = (52 mL / 4) / (80 mL / 4/hour)
Time = 13 hours / 20
Time = 0.65 hours
Time = 0.65*60 = 39 minutes
Therefore, it will take 39 minutes to run the 52 mL piggyback at a rate of 80 mL per hour.
