if something travels at the speed of 149,896,229 meters per second and I need to know how many seconds it will take it to travel 500 meters, do I need to divide 500 with that number? Like 500/149,896,229?
All this workload got me confused...no solutions pls just tell me if I am doing it right!

First one to get all correct gets points:
1) 5 x 0
2) 0 / 5 (Zero divided by five)
3) Peterpan x Darth Vader

A parsec is approximately 3.1 X 10^16 meters. If the distance to the farthest observable galaxies is approximately 1.62 X 10^9 parsecs, approximately how many meters is it to the farthest observable galaxies?

I don't even know what it's asking let alone where to start!

A young doctoral candidate was taking his orals. He had with him his super-high-tech calculator and several reference books containing all the formulas he needed. One crusty old professor posed the following math problem.

"You have a ball with a cylinderical hole through the middle. The height of the cylinder (hole) is 6 inches. When submerged in a bucket of water, it displaces about 113.09724 cubic inches." (Which the PhD candidate immediately recognizes as 36π in^3.)

Now sez the professor, "What is the diameter of the ball before we put the hole in it?"

The candidate's degree depends on his answer. What should it be?

When I'm asked about the meaning of pi, the answer is simple: If you measure the circumference and the diameter of ANY circle, you will always find that the circumference is approximately 3.14 times as big as the diameter. That number, 3.14... is pi.

Now, how do I explain "e" in simple terms that even a kid can understand?
