Answer:
The winner ran at an average of 12.39 miles per hour.
Step-by-step explanation:
In order to find this, we first need to convert the minutes and second into hours. This way we can add them to the 2 hours and then solve. We do this by dividing minutes by 60 and seconds by 360 since those are the unit rates.
5 mins/60 = .083 hours
11 secs/360 = .031 hours
2 + .083 + .031 = 2.114 hours
Now we take our 2.114 hours and divide the miles by that number to get the miles per hour.
26.2 miles / 2.114 hours = 12.39 mph
