Answer:

I think the actual length would be 75 inches. ( i'm not totally sure though C: )

Step-by-step explanation:

So, since the scale factor is 1 : 12, the model is 1/12 of the actual. So, multiply:

6.25 * 12 = 75

So, the actual length would be 75 inches.

To check:

75/6.25 = 12!

Answer:

9 Miles to be specific 8.95

Step-by-step explanation:

3 miles = 4.83 km

4.83 km = 4830 m

60 seconds X 45 =2700 Seconds

4830 divided by 2700 = 1.78 m/s

you want to know the distance so its speed X time

135 minutes X 60 seconds = 8100 secs

1.78 m/s X 8100 =14418 meters

14418 = 14.418 km

14.418 km = 9 miles

P.S. There is a shorter version but i think this is simpler for me and I use metric units.
