Two trains leave the same station at the same time but in opposite directions for faster train travels at an average speed of 75 miles per hour and the slower train travels at an average speed of 60 miles per hour and how many hours will they be 715 miles apart

715 / (75 + 60) = 5.296 h

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
