Interpret complex expressions by treating meaningful sub-expressions as single units.

Interpret a quotient as a unit rate or average

Problem

An object travels a distance of \(d(t)~\text{units}\) in \(t~\text{hours}\). What does \(d(t)/t\) represent? Identify what the numerator and denominator measure, give the quotient's units, and state what the quotient means.

Answer choices

Choose your path.

Preview only

numerator = d(t); denominator = t; quotient unit = hours/distance; role = inverse speed

numerator = t hours; denominator = d(t) distance; quotient unit = hours/distance; role = time per distance

numerator = d(t) distance units; denominator = t hours; quotient unit = distance units/hour; role = average speed

numerator = d(t); denominator = t; quotient unit = distance units; role = total distance
