See Explanation

Step-by-step explanation:

Given

$T_1 = 2\ hours$ ---------- A to B

$T_2 = 4\ hours$ ---------- B to C

Required

Determine the average speed of Mr. Ali's journey

To do this, we have to calculate the total distance covered.

i.e.

Distance = Town A to B + Town B to C

$Total\ Time = T_1 + T_2$

$Total\ Time = 2 + 4$

$Total\ Time =6$

The distance between the towns are not given. So, I'll make an assumption.

-------------------------------------------------------------------------------------------------------------

Assume:

Town A to B = 5km

Town B to C = 10km

$Total\ Distance = 5km + 10km$

$Total\ Distance = 15km$

-------------------------------------------------------------------------------------------------------------

Average Speed is then calculated as:

$Average\ Speed = \frac{Total\ Distance}{Total\ Time}$

$Average\ Speed = \frac{15}{6}$

$Average\ Speed = 2.5km/hr$
