Dimensions are the most basic or fundamental quantities that we can measure. Dimensions are not

units, they are more fundamentals, of which there are three that are the most common, these are

Mass $[$M$],$ Length $[$L$]$ and Time $[$T$].$

A runner runs $100$ yards in $10$ seconds. Using dimensional analysis techniques:

i$.$ Calculate the runner$$s rate in miles per hour.

ii$.$ Calculate time required to run $100$ meters.
