1 answer:
Average velocity = total displacement / total time
Total displacement is 25 yards.
Displacement is defined to be the change in the position of an object. Here displacement is 25 yards as firstly he walks 40 yards and again comes back 40 yards so he comes to original starting point. Now he again walks 50 yards and comes back 25 yards, so he is 25 yards from his starting position, hence displacement is 25.
Total time = 10 minutes
Average velocity = = 2.5 yards per minute.

Answer: Surface area is equal to 200
Volume is equal to 333.33
Step-by-step explanation:
First, let's do surface area.
The surface area of a pyramid is equal to 1/2(perimeter of base)(lateral height) + area of the base
The perimeter of the base is 10(4) = 40; as the base is a square with a side length of 10.
The lateral height is given as 5 cm.
The area of the base is 10(10) = 100.
We can plug those numbers into the equation to get 1/2(40)(5) + 100, which comes out to be 200.
Now for volume.
The volume of a pyramid is equal to 1/3(area of the base)(height).
We already have the area of the base, which is 100.
The height is given as 10 cm.
Plugging those numbers into the equation, we get 1/3(100)(10), which is 1000/3 or about 333.33.
