Based on the information given, the speed is 20 miles per hour.
From the information given, the winner of the local triathlon swam 0.5 miles, biked 15 miles and ran 2.5 miles and he finished the race in 54 minutes.
Note that 54 minutes = 0.9 hour.
The speed will be:

Answer:
Step-by-step explanation:
Think of drawing a right triangle, with the hypotenuse connected to points A and B. The hypotenuse, or the distance between A and B is 2√10. 2√10 is the same thing as √40. Thus, because of Pythagorean theorem, a^2 + b^2 = 40. One combination would be a=2 and b = 6 and another would be a = 6 and b = 2. Thus, the two places point B could be are (3,7) and (7,3).
