How to solve #12 can't seem to figure it out after spending 20 mins on it
Ilia_Sergeevich [38]
The area of one of the triangular lateral faces is

\dfrac{401.48-166.28}6=39.2

You're told that the slant height, which is the same as the height of the triangular face, is 9.8, so you have

39.2=\dfrac12\times9.8\times b

where b is the length of the base of the triangle, which is also the same as the side length of the base of the pyramid. So

b=8

Answer:

  D.  61 mi/h

Step-by-step explanation:

The travel time is 16:52 -8:13 = 8:39 hours, or 8.65 hours. Then the speed is ...

 speed = distance/time = 527.65 mi/(8.65 h) = 61 mi/h

_____

<em>Additional comment</em>

It is often convenient to use "military" or "24-hour" time for calculations of time periods that extend over noon or midnight. For this purpose, 12 gets added to the hour number in the afternoon (pm). Of course, 39 minutes is 39/60 hours. That is found to be 0.65 hours by performing the division of 39 by 60.
