Problema Solution
The conversion factor relating miles to meters is 1mile=1610m.
The speed of light is 3.00×108 m/s. How fast is this in miles per hour (miles/h)?
Answer provided by our tutors
1 mile = 1610 m
1 m = 1/1610 mi
1 hour = 360 sec
1 sec = 1/360 hr
3.00×10^8 m/s = 3X(10^8)*(1/1610)/(1/360) = 360X3X(10^8)*(1/1610) =
= (360X3/1610)X10^8 =
= 67.08X10^6 mi/h
