First you want to understand that every time a radio wave goes 300,000,000 meters a second passes, literally what meter per second means. of course it doesn't go that far, it goes 384,000 one way and then the same distance back, which makes 768,000. Under a third of the distance to make 1 second, so it will be less than one second.

You also want to understand the formula for speed. speed = distance / time. Whch also means, to find time you can change it to be time = distance / speed. And hey, we have distance and speed. 768,000 / 300,000,000 = .00256, I'll leave the significant figures to you unless you need help with them. but that's .00256 of a second. or .00256 s

On a car trip , the number of miles driven , m , is proportional to the number of gallons of gas used , g , as shown in the tabl

FrozenT [24]

Answer:

m = 32g

Step-by-step explanation:

The proportion between m and g can be written ...

m = kg

where k is the constant of proportionality.

We can find its value by dividing by g:

k = m/g

Using any pair of corresponding values from the table, we find ...

k = 64/2 = 32

The relationship between m and g can be expressed by the equation ...

m = 32g
