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

17/3 most likely it depends on what was needed
A. 4x-6y-14 = 0
Math & Reasoning:
You cannot simplify 4x-6y=14 any other way than subtracting 14 from both sides. You could solve for X and Y, but it'd be a long process and by the time you did that you would have it in it's most simplified form.
Answer:
cubic meter of clay will be used to create all the pyramids
Step-by-step explanation:
The remaining part of the question is given in the attached file
Solution
The total clay used is equal to the sum of volumes of two triangular and three rectangular pyramids.
For Rectangular Pyramid,
Volume of three rectangular pyramids
Substituting the given values in above equation, we get -
cubic centimeter
For triangular Pyramid,
Volume of two triangular pyramids
cubic centimeter
Total clay used = Volume of 3 rectangular pyramid + volume of 2 triangular pyramid Cubic centimeter
