Answer :
Final answer:
Robert will take 30 seconds longer than Luke to run a 3600 foot race, based on their respective speeds from practice. Therefore correct option is A
Explanation:
The student has asked about comparing the time it will take for Luke and Robert to complete a race based on their individual practice times and speeds. To solve this, we first calculate the speeds at which Luke and Robert ran during practice.
Luke's speed is 2700 feet in 3 minutes, which is 900 feet per minute. Robert's speed is 3200 feet in 4 minutes, which is 800 feet per minute.
Next, we need to find out how long it will take each of them to run 3600 feet.
For Luke: Time = Distance / Speed
= 3600 feet / 900 feet per minute
= 4 minutes.
For Robert: Time = Distance / Speed
= 3600 feet / 800 feet per minute
= 4.5 minutes (or 4 minutes and 30 seconds).
Thus, the difference in time is 0.5 minutes, which is the same as 30 seconds. Therefore, the correct answer is A. 30 seconds.
