A biker must circle a 12-mile track twice. His average speed must be 60 mph.
So, the average time required to cover the distance is 
hours.
Now, on his first lap, he averaged 50 mph.
So, he covered this 12 miles track in 
hours.
Hence, he has to cover the next 12 miles track in (0.4 - 0.24) = 0.16 hours.
Therefore, his average speed in the second round must be 
mph to qualify. (Answer)
Answer: Last option.
Step-by-step explanation:
By definition, a pyramid has a base (which is a polygon) and three or more triangular faces.
You can observe in the image that the the figure has three triangular faces and a triangular base. The sides of the base are all equal, then it is an equilateral triangle.
Then, since the base of the tringular pyramid is an equilateral triangle, the faces are also equilateral triangles.
Therefore, the three-dimensional figure that can be made from the net shown, is:
A triangular pyramid that must have 4 congruent and equilateral triangles.
