The time it takes to travel 111 miles at a rate of 65 miles per hour is approximately 1.71 hours, or about 1 hour and 42 minutes. The formula for discovering time is: distance divided by rate.
Solving for time in this problem requires dividing 111 miles by 65 miles per hour to obtain the number of hours the trip takes. The basic formula of "distance equals rate times time" is used to find any of the three variables when the other two are known. To find rate requires dividing distance by time. Rate is another word for expressing speed in such equations.
