The first step is to find how long he drove in yards. yards. Now, we need to convert it into feet. A yard is exactly three feet, meaning that he drove feet. Finally, we need to find how many miles he drove. It is known that there are 5280 feet in a mile, so you just need to divide the number of feet he drove by the number of miles to find that he drove 210998.8/5280=39.96 miles. Hope this helps!
