    Answer:

    1)speed=12.5 miles/hr

    2)time=56.25hr or 0.36hr(i prefer this one..check explanation)

    Step-by-step explanation:

    speed=distance/time

    s=3.75/0.3=12.5

    speed is = 12.5 miles/hr

    2nd part:

    speed=distance/time

    so time=speed*distance

    : time=12.5*4.5=56.25hr(hard to believe the answer)

    or

    miles:hours

    3.75:0.3

    4.5:x

    cross multiply

    4.5*0.3/3.75=0.36

    x=0.36hrs (answer is believeable)
