Answer:
9 mph
Step-by-step explanation:
-let x be the speed of current and t be time. The speed equation for both directions can then be represented as:
#Since t is equal in both, we can do away with t.
#We the divide the downstream equation by the upstream equation as:
Hence, the boat's speed in still water is 9 mph
Answer:
(5,7.5) (12,18) (18,27)

This is a square, and so all the sides will be the same measurements. Note that you are given an area, so you'll have to root the total area to get a side.
√400 = 20
One side's measurements is 20 in
