Explanation:

Step1: Find the current speed

The maximum speed is 129 meters per minute. The current speed is one - third of the maximum speed, so we calculate $\frac{1}{3}\times129$.
$\frac{1}{3}\times129 = 43$ meters per minute.

Step2: Use the formula \(t=\frac{d}{v}\) (time = distance / speed)

We know the distance \(d = 602\) meters and the speed \(v=43\) meters per minute. So we calculate \(t=\frac{602}{43}\).
\(\frac{602}{43}=14\) (since \(43\times14 = 602\)).

Answer:

14
