Finding total minutes in a mountain bike race

You are competing in a mountain bike race.  Your average speed is 10 mi/hr.  If the racecourse is 65 miles long, how many minutes will it take you to finish the race?

---

65 miles ÷ 10 mi/hr
= 6.5 hours   {divided distance by rate to get time    distance = rate x time}

      {60 minutes in 1 hour}


6.5 x 60   {multiplied 6.5 by 60 to get total minutes}
= 390 minutes   {multiplied}
