What distance would Mario travel if he drove for 4 3/4 hours at 70 miles per hour? Assume that a steady speed was maintained.

You would turn the mixed fraction into a improper fraction by multiplying the denominator by the whole number then you add the numerator. So, your improper fraction will be 19/4. Now do 19/4 * 70 and you get 1330/4 or 332 2/4
