Long-distance 5737

The long-distance bus driver went 2/5 of the route length in the morning and 1/3 of this length in the afternoon. He still has 60 km to the finish. How long is the long-distance bus route?

Correct answer:

s =  225 km

Step-by-step explanation:

$$\begin{gathered} \frac{2}{5}s+\frac{1}{3}s+60=s \\ 2/5\cdot s+1/3\cdot s+60=s \\ 4s=900 \\ s=\frac{900}{4}=225 \\ s=225=225\text{km} \end{gathered}$$
