Given:
L = 1.2 kilometers = 1200 meters – the distance run by the athlete;
v = 18 kilometers per hour = 6 meters per second – the speed of the athlete.
It is required to determine t (second) – the time during which the race lasted.
To determine the time of the race, you need to use the formula:
L = v * t, hence:
t = L / v = 1200/6 = 200 seconds (approximately 3.3 minutes).
Answer: the athlete’s race lasted 200 seconds (approximately 3.3 minutes).
