how long would it take a radio wave with a frequency of 7.25 x 10to the 5th to travel from Mars to earth if the distance is approx. 8.0 x 10 to the 7th?
Answered by DrBob222
If the distance is 8.0E7 WHAT? miles? km? feet? gallons?
distance = rate x time.
Radio waves travel at 3E8 m/s

Oh I am sorry, the distance between mars and earth is measured in kilometers.
Answered by DrBob222
Substitute into distance = rate x time and solve for time. You will need to change the distance from km to m or rate from m/s to km/s.

reverse the reciprocal and divide by 12 and measure by comcast remote. Then rub with lemon juice to remove stain. After, crack the egg with 2 fingers as that is the most effective way to do so. Last but not least, add 2 1/2 cups of ice tea vodka to take it all down. This should get you to your desired result.
