I'm having some trouble with a few problems that I'd really appreciate some help with. 1.) The velocity of a space shuttle is 8 x 10^3 meters/seconds I have to convert this to kilometers/hours. I know there are 1000 meters in a kilometer, and 3600 seconds in an hour. Next I have to convert meters/seconds to miles per hour! However, I don't know how to put these into an equation to solve. :( The same goes for the following problem: 2.) 3 x 10^-1 joules/minutes How many watts is this? I know 1 watt = 1 joule/seconds, but again don't know how to put it into an equation. The next part is how many miliwatts is produced? I am just looking for how to put these into a solvable equation--I can take it from there. :) Help would be greatly appreciated!
