Answer:
325 km
Step-by-step explanation:
we are given the average speed of Moana's motorcycle and we want to figure out her total distance to do so convert hours to minutes so,
therefore,
[tex] \begin{array}{ccc} \rm 60\: minutes \implies 50kph \\ \displaystyle\rm1 \: minutes \implies \frac{50}{60} kph \\ \\ \displaystyle \rm390 \: minutes \: \implies \frac{50}{60} \times 390kph \\ \xrightarrow{ \rm reduce \: fraction} \displaystyle \frac{5}{6}\times 390 \\ \displaystyle \xrightarrow{ \rm \: reduce\: fraction}5 \times 65 \\ \xrightarrow{ \rm \: simplify\: multiplication}325\end{array}[/tex]
hence,
she travels 325 km in total
