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)
