Choice B
For every 3 rabbits there are 8 total animals
Velocity Against Current = 108 / 3 = 36 km/hour
Velocity With Current = 108 / 2 = 54 km/hour
"vsw" means velocity in still water "cs" means current speed
vsw -cs = 36
vsw +cs = 54 Adding both equations
2 * vsw = 90
velocity in still water = 45 km/hour
current speed = 9 km/hour

The inequality of this on the number line would be less than which looks like this
You build one raised garden box that is 12 feet by 6 feet and 10 inches tall. the supply store sells garden soil in cubic yards.
The volume of box is 12 *6 * 10/12 = 60 ft3(1 in =1/12ft)
and 1yd3 = 27ft3
= 60/27 = 20/9 = 2,22 cupid yards
Price of soils = $5 * 2.22 = $11.11
