Final answer:
The distance between Anthony's and Kennedy's houses is calculated using the formula Distance = Speed × Time. With a speed of 5 mph and time of 0.5 hours, the correct answer is 2.5 miles.
Step-by-step explanation:
The question can be solved by using the formula for distance in the context of speed and time, which is:
Distance = Speed × Time
In this scenario, Kennedy rode his bike for 0.5 hours (Time) at a speed of 5 mph (Speed). Thus, the distance (Distance) that Anthony lives from Kennedy can be calculated as follows:
Distance = 5 mph × 0.5 hours = 2.5 miles
Therefore, the correct answer is: A. 2.5 miles.
