Answer:
about 4hours and 45 minutes
Step-by-step explanation:
> Standard triathlon
0.93-mile swim, and 25-mile bike ride in 3.5 hours
6.2-mile run in ? hours
> If it takes (12-minute/ 1mile) then will have (? minutes/ 6.2 miles.)
So we need to find an equivalent fraction of 12/1 that has x/6.2.
(12min/ 1 mile) = (x minutes/ 6.2 miles) , cross multiply
1*x = 12*6.2
x = 74.4 minutes will take to run 6.2 miles
> The rest of the ride times are given in hours so will convert or minutes to hours
60 minutes = 1 hours
74.4 minutes = x hours
x= 74.4 *1/ 60 = 1.24 hours
x = 1.24 hours will take to run 6.2 miles
> Approximately how long will it take her to complete the triathlon?
0.93-mile swim, and 25-mile bike ride in 3.5 hours
6.2-mile run in 1.24 hours
3.5 +1.24 = 4.74 hours which is about 4hours and 45 minutes
