Kenneth drove 184.25 miles in 3 7/20 hours. what was his average speed

To solve this problem, all you have to do is set up a proportion, letting x represent Kenneth's average speed per hour.

184.25/3.35 = x/1

Now, we use cross products, or the multiplication of the numerator of one fraction times the denominator of another fraction, and setting them equal to one another.

3.35x=184.25

Finally, we divide both sides by 3.35, because it's the coefficient of x, and we are trying to get the variable x alone.

x=55

Therefore, Kenneth's average speed was 55 miles per hour.
