Final answer:
Sabrina will take 837.99 seconds to run 1500 meters.
Step-by-step explanation:
To calculate the time it takes for Sabrina to run 1500 meters, we can use the formula:
Time = Distance / Velocity
Given that Sabrina's average velocity is 1.79 m/s and the distance is 1500 meters, we can substitute these values into the formula:
Time = 1500 m / 1.79 m/s = 837.99 seconds.
Therefore, the correct answer is a) 837.99 seconds.
