Answer:

He will have paddled the canoe for 4 km.

a. The distance paddled out is equal to the distance paddled returning.

Step-by-step explanation:

Let <em>d </em>be the distance that Roger Waters paddled out.

Let <em>t </em>be the time for the travel he paddled out and <em>t' </em>be the time for returning.

Then from the formula time=\frac{distance}{speed},

<em>t </em>= \frac{d}{4} and <em>t' </em>= \frac{d}{2}

Total time for the journey = 1 hour 30 minutes = 1.5 hours

So, <em>t</em> + <em>t'</em> = 1.5

\frac{d}{4} +\frac{d}{2} =1.5

\frac{3d}{4} =1.5

3<em>d</em> = 6

<em>d</em> = 2 km

The total distance he will have paddled the canoe = 2<em>d</em> = 2(2) = 4 km.

Clearly, the distance he paddled out = the distance he returned.

Hence, the correct option is A.

Given the figures are similar, calculate the perimeter of the ABCDE.
Vsevolod [243]

Let the length of side AB be $x$, then

\cfrac{x}{2}=\cfrac{12}{4}\Rightarrow4x=24\Rightarrow x=\cfrac{24}{4}=6.

Therefore, the perimeter of ABCDE is 2(12) + 2(4) + 6 = 24 + 8 + 6 = 38 in.
