Transported 67924

On Thursday, 240 skiers had to be transported, and two buses took 30 minutes to do so. If there were 660 skiers on the piste and three buses were used, how long did the transport take on Saturday?

Correct answer:

x =  55 min

Step-by-step explanation:

$$\begin{gathered} n_1=240 \\ {n}_2=660 \\ {t}_1=30 \\ {a}_1=2 \\ {a}_2=3 \\ x=\frac{n_2}{n_1}\cdot \frac{a_1}{a_2}\cdot t_1=\frac{660}{240}\cdot \frac{2}{3}\cdot 30=55\text{min} \end{gathered}$$
