Aboat moves 60 kilometers east from point a to point b. there, it reverses direction and travels another 45 kilometers toward point a. what are the total distance and total displacement of the boat?

Total distance = 60 + 45 =  105 km , Total displacement = 60 - 45 = 25 km.

Step-by-step explanation:

Given : A boat moves 60 kilometers east from point A to point B. There, it reverses direction and travels another 45 kilometers toward point A.

To find :  What are the total distance and total displacement of the boat?

Solution : Let boat's initial point is A.

It moves form A to B = 60 km.

it reverse its direction and move toward A = 45 km at any point .

So, Total Distance = Total path covered by boat.

Total distance = 60 + 45 =  105 km.

Total displacement = initial point - final point.

So, Total displacement = 60 - 45 = 15 km.

Therefore ,Total distance = 60 + 45 =  105 km , Total displacement = 60 - 45 = 15 km.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
