Brian plans to complete a 100-mile bike race for charity. According to his registration materials, he will need to ride at an average speed of 12.5 miles per hour if he wants to complete the course before it closes. On a pratice ride the week before the race, Brain rides 60 miles and trackes his speed. For the first 30 miles, his average speed is 16 miles per hour, and for the next 30 miles, his average speed is 15 miles per hour. If Brian can match these speeds for the first 60 miles of the charity race, then he rests for that total of 1 hour after that, what approximately speed must he maintain for the last 40 miles in order to complete the ride on time?
