Answer to Problem 42P

The length of school bus should be measured in meters.

Explanation of Solution

Given:

Length of a school bus

Calculation:

There are 2 systems for measurement, one is customary system and other is metric system.

Customary has been used historically for various measurements, while metric system is widely accepted due to ease of calculations.

Various units of length in metric system are millimeters, centimeters, meters, kilometers etc.

Since, school bus is quite bigger than normal small things like paper, DVD. And is comparable to things measured in meters like width of road, height of elephant.

It is reasonable to say that length of school bus should be measured in meters.

Conclusion:

Hence, the length of school bus should be measured in meters.
