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

Interpret a difference of two expressions

Problem

For \(d_A(t)-d_B(t)\), both distances in the same units at time \(t\), identify minuend, subtrahend, difference role/unit, and sign meaning.

Answer choices

Choose your path.

Preview only

minuend = runner A distance; subtrahend = runner B distance; difference = A's lead only; negative impossible

minuend = runner A distance; subtrahend = runner B distance; difference = signed A-minus-B distance gap; unit = distance units; positive = A ahead; negative = A behind

minuend = runner A distance; subtrahend = runner B distance; difference = total distance traveled

minuend = runner B distance; subtrahend = runner A distance; difference = signed A-minus-B gap
