You will need to measure it because your overall system also effects what it will flow. Going by the rating alone, your blue pump would have filled a gallon in 32 seconds.
88gph for the blue. 88gph/60minutes in an hour =1.466 gallons per minute. 60 seconds in a minute/ 1.466 gallons = 40.9 seconds per gallon.
