Final answer:
Trax would take 16 hours to complete a 48-mile ultra-marathon walking at an average speed of 3 mph, using the formula Time = Distance ÷ Speed.
Step-by-step explanation:
The subject of the question is Mathematics, specifically dealing with concepts related to time, distance, and speed calculations. We need to calculate the amount of time it will take for Trax to complete a 48-mile ultra-marathon if he walks the entire distance at an average speed of 3 miles per hour (mph).
To find the time, we can use the formula: Time = Distance ÷ Speed. Given Trax's walking speed of 3 mph and the marathon distance of 48 miles, we can perform the calculation as follows:
Time taken to complete the race = 48 miles ÷ 3 mph = 16 hours.
Therefore, it will take Trax 16 hours to walk the entire 48 miles of the ultra-marathon.
