To find the distance of the swimming event, we can subtract the distance of the running event from the total distance of the race.
The total distance is 7.13 miles, and the running event distance is 6.2 miles.
Distance of swimming event = Total distance - Running distance Distance of swimming event = 7.13 miles - 6.2 miles Distance of swimming event = 0.93 miles
Therefore, the distance of the swimming event is 0.93 miles.
