Length = 7 Width = 2
Step-by-step explanation:
L = Length
W = Width
L=9w-11
2L+2W=18
2(9W-11) + 2W = 18
18W - 22 +2W = 18
20W -22 = 18
20W = 40
W = 2
L = 9(2)-11
L=18-11
L=7

Answer:
6 PM
Step-by-step explanation:
The truck has a 2 hour head start. It is moving at 45 km/h, so it is 90 km ahead.
If t is the time after 8 AM, then the distance between the truck and the station is:
d = 90 + 45t
The distance between the van and the station is:
d = 54t
When the distances are equal:
54t = 90 + 45t
9t = 90
t = 10
It takes 10 hours after 8 AM for the van to catch up with the truck. So the time would be 6 PM.
