A trip to the Dry Peak

Calculate what percentage of the trip from Strečno to peak Suchý (Dry Peak) is longer than the descent back. The team of tourists (Palo, Peter, and Andrew) 's rise took 4:11 and descent 3:51.

Correct answer:

p =  8.7 %

Step-by-step explanation:

$$\begin{gathered} t_1=4:11=4hr11min=4+\frac{11}{60}=4.1833hr\doteq 4.1833 \\ {t}_2=3:51=3hr51min=3+\frac{51}{60}=3.85hr=3.85 \\ p=100\cdot \frac{t_1-t_2}{t_2}=100\cdot \frac{4.1833-3.85}{3.85}=8.7\% \end{gathered}$$
