The speed of light is approximately 93 * 10^4 miles per second. This approximate speed is how many miles per hour?
Choose the correct choice from the following options:  A) 1,11 * 10^7  B) 3,35 * 10^6  C) 1,11 * 10^8  D) 1,86 * 10^8  E) 3,35 * 10^7
The easiest way to answer this question is by POE, it does not require any calculation (answered in 30seconds). In one hour there are 3600 seconds, therefore speed in miles/hour will be.   (.93*10^4)*3600 = (.93*10^4)*(3.6*10^3) = some number*10^7...   The key is realizing that thesome numberhas to be bigger thatn .93(because .93*3.6), and the only answer that fits that is 3,35 * 10^7.
