A water pipe freezes and cracks on a cold night. <em> (D)</em>
There are three physical changes going on in this scenario:
1). The air gets cold and dark at night.
2). The water in the pipe freezes and expands.
3). The pipe cracks.
There are no chemical changes in the description.
V=D/T - formula for speed
88 km/h = D / 0.75 hours - multiply speed and time
66 km= D
D is distance
D= 66 km
Hope this helps
