Using Chebyshev's Theorem, the minimum percentage of commuters in has a commute time within 2 standard deviations of the mean is of 75%.
<h3>What does Chebyshev’s Theorem state?</h3>
When we have no information about the population distribution, Chebyshev's Theorem is used. It states that:
- At least 75% of the measures are within 2 standard deviations of the mean.
- At least 89% of the measures are within 3 standard deviations of the mean.
- An in general terms, the percentage of measures within k standard deviations of the mean is given by
.
Hence, the minimum percentage of commuters in has a commute time within 2 standard deviations of the mean is of 75%.

Just plug in the coordinates to each answer choice with a slope of 3 (ACD) and see which one is true
Speed = distance / time
speed = 170/2.5
speed = 68 km per hr
The answer would be:
