If a marathon runner averages 9.51 mi/hr, how long does it take him to run a 26.220-mile marathon. express your answers in hours, minutes, and seconds.

Explanation:

Speed of the marathon runner, v = 9.51 mi/hr

Distance covered by the runner, d = 26.220 mile

Let t is the time taken by the marathon runner. We know that the speed of the runner is given by total distance divided by total time taken. Mathematically, it is given by :

t = 2.75 hours

Since, 1 hour = 60 minutes

t = 165 minutes

Since, 1 minute = 60 seconds

t = 9900 seconds

Hence, this is the required solution.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
