Question 429525: The orbit of Planet A has a mean distance from teh sun of 2.7x10 7 (power) miles while the orbit of Planet B has a mean distance from the sun of 6.5 x 10 7 (Power)miles. How long would it take a spacecraft traveling at 1.900x10 3 (Power) miles per hour to travel from the orbit of Planet A to the Orbit of Planet B. They would like the answer in scientific notation.
I am not good with word problems (I have a language disorder). I tried to visualize it, but I don't really know where Planet A is from B, same side, or does it matter?
Please help.

Question 429660: Albert Einstein in his theory of relativity showed that if a person travels at nearly the speed of light, then time slows down significantly. Suppose that there are twins; one remains on Earth and the other leaves in a very fast spaceship having velocity v. If the twin on Earth ages T0 years, then according to Einstein the twin in the spaceship ages T years, where
T(v) = T¬0 sqrt 1-(v/c) squared
In this formula c represents the speed of light, which is 186,000 miles per second.
(a) Evaluate T when v = 0.8c (eight-tenths the speed of light) and T¬0 = 10 years.
(Hint: Simplify without using 186,000 miles per second.)
(b) Interpret your result.
