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)?

Speed of light = 3.00 x 10^8 m/s

1 mile = 1610 m, it implies that 1 m = 1/1610 mile

1 s = 1/3600 hour

Speed of light = (3.00 x 10^8 x (1/1610) mile) / (1/3600) hour

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
