The average speed for the race is 0.281 minutes/mile.
Step-by-step explanation:
Total distance covered = swam distance + bike distance + ran distance
⇒ 1 mile + 25 miles + 5 miles
⇒ 31 miles.
Total time taken = swam time + bike time + ran time
⇒ 25 minutes + 45 minutes + 40 minutes
⇒ 110 minutes
Average speed = total distance / total time
⇒ 31/110
⇒ 0.281 minutes/mile
