If the speed of light is 3x105 km/s and 1 km=0.62 miles, what is the speed of light in miles per hour?

Sagot :

Answer:

6.7 x 10^8 mi/hr

Explanation:

Do the math with units ONLY

   km/s    *   miles/ km   *  s/hr   =   mi / hr    ( ...as the km and s cancel out)

                           now.... put in the numbers

     3 x 10^5   km/s   *   .62  mi/km  * 3600 s / hr  = 6.7x 10 ^8  mi/hr
