The way I did it was to break it down.
864m / 12h = 72mph
72mph * 7h = ?m
Hope this helped.
I'm sure you can solve it from there. ;)

Let distance traveled in 7 hours be D

Then: 864%2FD+=+12%2F7

12D+=+864%287%29 ----- Cross-multiplying

D, or distance traveled in 7 hours = 864%287%29%2F12______72cross%28864%29%287%29%2Fcross%2812%29_______72(7), or highlight_green%28504%29 miles
