here

height of the prism ( H )= 6m

area of a triangle ( A )= 1/2 × base × height

= 1/2 × 3 × 4

= 6 m^2

we know ,

volume of prism = H×A

= 6m × 6m^2

= 36 m^3

therefore volume of the prism is 36 m^3

A row team paddles 30 miles upstream in 2 hours and 30 miles downstream in 45 minutes. How fast can the row team paddle in still
sp2606 [1]

Answer:

Rate in still water = 27.5 mph

Current's rate = 12.5 mph

Step-by-step explanation:

Let

x mph = row team rate in still water

y mph = current's rate

<u>Upstream:</u>

Distance = 30 miles

Time = 2 hours

Rate = x - y mph

Then

30=2(x-y)

<u>Downstream:</u>

Distance = 30 miles

Time = 45 minutes =\dfrac{3}{4} hour

Rate = x + y mph

Then

30=\dfrac{3}{4}(x+y)

From the first equation:

30=2(x-y)\Rightarrow 15=x-y

From the second equation:

30=\dfrac{3}{4}(x+y)\Rightarrow 40=x+y

Add these two equations:

15+40=x-y+x+y\\ \\2x=55\\ \\x=27.5\ mph

Subtract these two equations:

40-15=x+y-(x-y)\\ \\25=x+y-x+y\\ \\2y=25\\ \\y=12.5\ mph
