Answer: 
<u>Step-by-step explanation:</u>
Let the speed off the walk way be x and speed of the walkway be y
x+y=6....i
x-y=2....ii
adding the above equation we get:
2x=8
thus
x=4 ft/s
and
y=6-4=2 ft/s
thus the speed off the walk way is 4 ft/s
the speed of the moving walkway is 2 ft/s
1) x=1
2) x=2.9
3) x=-10
4) x=?
5) IDK
700ml=23.6698fl
64-23.6698=40.3302
40.3302fl
