According to Star Trek, Warp 8 is 8 times the speed of light. If the star ship Voyager can travel at Warp 8, how many miles can it travel in a year? Write your final answer in scientific notation and show at least one step of your work.

    okay. to make matters simple, we generally assume the speed of light to be 300000000 m/s or 3X10^8 m/s so, what is Warp 8 then? What is that speed equal to?

    you must always say what that number means. 8 X 299 792 458 could mean feet, or pounds or number of fish you caught last year. what is it?

    okay. so we have the speed. now, what is the distance traveled in a year? the formula for distance is speed X time. so how much time is one year?

    okay. so a minute has 60 seconds. and hour has 60 minutes, a day has 24 hours. a year has 365 days. so the total number of seconds in a year is 60 X 60 X 24 X 365

    are you familiar with meters? it is just a measure of distance. One meter is roughly equal to one yard. so don't get confused by the word 'meter'

    okay. so if my speed is 10 m/s, I travel 100 meters in 10 seconds. Using the same logic, if my speed is 2398339664 m/s , how many meters do I travel in 31536000 seconds?

    okay. so 7.563403964E16 meters is the answer. That is also the scientific notation. Scientific notation simply means you take a number, say 123455 and express it as 1.23455 X 10^5. so the answer in your case is 7.563403964E16 which can also be written as 7.563403964 X 10^16

    The letter E in the answer means you multiply the number before E with 10^ the number after E so 7.563403964E16 means 7.563403964 multiplied by 10^16. so your answer in scientific notation is 7.563403964E16 meters or 7.563403964 X 10^16 meters.

    http://www.chem.tamu.edu/class/fyp/mathrev/mr-scnot.html http://en.wikipedia.org/wiki/Scientific_notation scientific notation is just a way to represent NUMBERS. It does not mean that you should change meters to miles or anything like that.

    you are welcome. note that E means the exponent. it doesn't always have to be 10.
