QuestionA motorist traveled from Town A to B, averaging $54 \mathrm{~km/h}$. If the first $\frac{1}{3}$ was at $45 \mathrm{~km/h}$ and he traveled 480 km after, find the speed for the last $\frac{2}{3}$.

Studdy Solution
Calculate the last part speed.
$$Last\, part\, speed = \frac{480 \mathrm{km}}{16 \mathrm{hours}} =30 \mathrm{km/h}$$The average speed for the last $\frac{}{3}$ of the distance was $30 \mathrm{km/h}$.
