Answer: B) 40 miles for 5 hours

Divide both values by 5 and we'll simplify that to 8 miles for 1 hour. This is the same as saying 8 miles per hour, or 8 mph.

The ratio 8:1 is read as "8 to 1", meaning the first value is 8 times that of the second value. Note how 40 is 8 times that of 5, ie 40 = 8*5.

In miles 365 million miles or 365,000,000
in km, 588 million km or 588,000,000

so
scientific notation=(number less than 10 and greater than or equal to 1) times 10^n

so
we need to move the decimal point 8 spaces to the left
to compensiate for that, we multiply by 10⁸ which will move it 8 to the right
so

365,000,000 mi=3.65 times 10⁸ mi
588,000,000 km=5.88 times 10⁸ km

those are the distances in scientific notation
