Q. Which is a better estimate for the distance of a road from one end of a city to the other?Choices:(A) 30kilometers(B) 30meters
City Size Consideration: First, let's think about the typical size of a city. A city usually stretches over a much larger area than just a few meters. So, we need to decide between kilometers and meters for a reasonable estimate of the distance from one end of a city to the other.
Unit Comparison: Next, let's compare the units. 30 meters is about the length of a small school or a large supermarket, which is way too short to be the distance from one end of a city to the other. On the other hand, 30 kilometers is a more realistic measure for such a distance, as it represents a much larger scale.
Final Distance Estimate: Therefore, considering the scale and typical dimensions of a city, 30 kilometers is a much better estimate for the distance from one end of a city to the other than 30 meters.
