A radio signal travels at
3.00 ⋅ 10^8 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of Earth if the satellite is orbiting at a height of 3.54 ⋅ 10^7 meters? Show your work.

This is my question in Algebra and was wondering how do I do it so I multiply them, divide them, subtracting, or adding?

  1. just remember your units.
    distance = speed * time, so

    time = distance/speed

  2. So it would be 3.00*10^7 * 3.54*10^7? To get the answer?

  3. excuse me? You want the time, right? They already gave you the distance

    time(s) = distance (m) ÷ speed (m/s)

    If you include your units, you will never be confused on what gets divided or multiplied. Your final answer must be in the correct units.

    You need to
    (a) read the question carefully
    (b) pay attention when help is given, not grab the first thing you see.
