Answer: Option C

A measurement of speed equaling (27.7 km/hour)

Explanation:

It is measurement of speed equaling (27.7 km/hour) because it is a factor used in dimensional analysis because it is a problem solving method that involve the use of number or expression which can be multiplied without affecting or causing a change in the value of the expression.

27.7km/he is not the exact number that can limit the precision of the calculated value or accurate value.
