Cable car

The cable car will carry 1280 passengers in 40 minutes. How many people will be transported in 2.5 hours?

Correct result:

n =  4800

Solution:

$$\begin{gathered} t_1=40\text{ min } \\ {t}_2=2.5\text{ h}\to \text{ min}=2.5\cdot 60\text{ min}=150\text{ min } \\ n=1280\cdot {\displaystyle \frac{t_2}{t_1}}=1280\cdot {\displaystyle \frac{150}{40}}=4800 \end{gathered}$$
