Question

The speed of light is 186000 miles per second about how many miles does light travel in an hour

5.2*10^1 miles
3.1*10^3 miles
1.1*10^7 Miles
6.7*10^8 miles

Answer 1

One hour is equivalent to 60 minutes and 1 minute is equivalent to 60 seconds, therefore:

60 minutes/hr * 60 seconds/minute = 3600 seconds/hr

At a rate of 186000 miles per second, light will travel 186000*3600 = 669,600,000 miles, which can be restated as 6.7*10^8 miles
