Answer 2

The length of the journey is 768 km.

Step-by-step explanation:

Given : A bus covers a certain distance in 16 hours. It covers half the distance at 40 km/h and the rest at 60 km/h.

To Find : The length of the journey ?

Solution :

We know, $\text{Distance}=\text{Speed}\times \text{Time}$

Let the total distance covered = x  = Length of journey

According to the question,

$\frac{x}{2}\times \frac{1}{40}+\frac{x}{2}\times \frac{1}{60}=16$

$\frac{x}{80}+\frac{x}{120}=16$

$\frac{3x+2x}{240}=16$

$\frac{5x}{240}=16$

$x=\frac{16\times 240}{5}$

$x=768$

Therefore, the length of the journey is 768 km.
