Final answer:
The equation that shows the relationship between time and distance is D = 60T. It would take Glenda 1/60 minutes to swim a mile at this rate.
Step-by-step explanation:
The equation that shows the relationship between time and distance is D = 60T. This equation means that distance is equal to 60 times the time (in minutes).
To find how long it would take Glenda to swim a mile at this rate, we can substitute the given distance of 1 mile into the equation. D = 1 mile and the equation becomes 1 = 60T. To find T, we divide both sides of the equation by 60, giving us T = 1/60.
Therefore, it would take Glenda 1/60 minutes to swim a mile at this rate.
