Answer:
Their average speed during the entire round trip = 24 miles per hour
Step-by-step explanation:
To determine:
What was their average speed during the entire round trip?
Information Fetching and Solution Steps:
- A cyclist travels at 20 kilometers per hour when cycling uphill
- 24 kilometers per hour when cycling on flat ground
- 30 kilometers per hour when cycling downhill
On a sunny day, they cycle the hilly road from Aopslandia to Beast Island before turning around and cycling back to Aopslandia.
Let us assume that that the road is uphill one way and downhill the other way
As we know that the formula of average speed
On the way out:
Say
on the way back:
So,
As
Therefore,
= 24 miles per hour
Hence, their average speed during the entire round trip = 24 miles per hour

Answer:
(a) points are; Y, X,V and Z
(b)a and b
(c) D
(d) a
(e) W
(f) line bisector.
(g) Y,X,W or VZW
(h)YXW or VZW
Step-by-step explanation:
(a)A point is an exact position on a plane surface usually indicated as a dot and has no size.In the figure, points are; Y, X,V and Z
(b) A line is a line of points which is extending infinitely in two directions.The lines appearing in this figure are; a and b
(c)A plane is a flat surface made of points which extend infinitely in all directions. The plane in the figure is D
(d)A line containing point V is that one which has the point V that extends infinitely in two directions. The line with point V is a
(e)An intersection point is where two lines meet at right-angle.The intersection point of line a and b is W
(f) A line that bisects another line segment into two equal parts is called a line bisector.
(g)Non-collinear points are those points which do not lie on the same line.In this case, points Y and X are non-collinear and points Z and V are also non-collinear
(h)A plane has two dimensions , extends without ending and its shape looks like that of a floor. Any three points not on the same line represents a plane.In this case, plane D is also called plane YXW
You just place the same numbers into the equation
Answer:
The answer is AB
Step-by-step explanation:
As A+B=AB
