Final answer:
To find the duration of the basketball game, divide the distance traveled by Kevin Durant, which is 4 miles, by his average speed of 2 mph, resulting in a game time of 2 hours.
Step-by-step explanation:
To determine how long the basketball game was, based on the information that Kevin Durant travels 4 miles on the basketball court at an average speed of 2 mph, we can use the formula:
Time (hours) = Distance (miles) ÷ Speed (mph)
Plugging in the values:
Time = 4 miles ÷ 2 mph
Time = 2 hours
Therefore, the correct answer to the question is (a) 2 hours.
