    Answer:

    1.88 minutes

    Step-by-step explanation:

    This question can be solved using speed, distance and time concept along-with use of computing fractions.

    Given

    Distance ran by Kirby = 3/4 of half mile

                                        = 3/4 of 1/2 mile = 3/4 * 1/2 mile = 3/8 mile.

    Speed of Kirby until she dropped out of race = 12 miles/hour

    Formula to calculate time = Distance/Time

    substituting value of speed of Kirby and distance covered by Kirby

    Time = (3/8) / 12 = 3/(8*12) = 1/32 \ hour

    Since one hour has 60 minutes 1/32 hour = (1/32) * 60 minutes = 1.88 minutes
