ANSWER:
60 km
STEP-BY-STEP EXPLANATION:
Given:
speed (v) = 120 km/hr
time (t) = 1/2 hr
We know that the formula for speed is as follows:
[tex]\begin{gathered} v=\frac{d}{t} \\ \text{ we solve for d} \\ d=v\cdot t \end{gathered}[/tex]We replace the values:
[tex]\begin{gathered} d=120\cdot\frac{1}{2} \\ d=60km \end{gathered}[/tex]The distance is 60 km
