Respuesta :

If she picks 3/4 gallons in 1/2 hours, then her rate is
                                            rate = (3/4) / (1/2) = 3/2 gal/hr
At a rate of 3/2 gallons per hour, she picks in two hours:
                                       gallons = rate * time
                                                     = 3/2 * 2
                                                     = 3
The answer is 3 gallons.
