Final answer:
To find how fast Taylor swims in miles per hour, divide the distance Taylor swims by the time it takes.
Step-by-step explanation:
To find how fast Taylor swims in miles per hour, we can use the formula speed = distance/time.
In this case, Taylor swims 1/2 mile in 1/3 hour, so we divide the distance (1/2 mile) by the time (1/3 hour):
speed = 1/2 mile / 1/3 hour = 1/2 mile * 3/1 hour = 3/2 miles per hour.
So Taylor swims at a speed of 1.5 miles per hour (option C).
