Final answer:
Jack's speed is calculated by dividing the total distance he runs, which is 3 laps or 1580 meters, by the time in seconds, giving a speed of 13.17 m/s.
Step-by-step explanation:
To calculate Jack's speed around the track, we need to use the formula for speed: speed = distance / time. Jack runs 3 laps around a 526 meter circular track, so the total distance covered is 3 * 526 meters. The time taken is 2 minutes, which is equivalent to 120 seconds in SI units.
Therefore, Jack's speed is (3 * 526 meters) / 120 seconds = 1580 meters / 120 seconds = 13.17 meters per second (m/s).
