Step-by-step explanation:
Given
[tex]T_1 = 2\ hours[/tex] ---------- A to B
[tex]T_2 = 4\ hours[/tex] ---------- 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
[tex]Total\ Time = T_1 + T_2[/tex]
[tex]Total\ Time = 2 + 4[/tex]
[tex]Total\ Time =6[/tex]
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
[tex]Total\ Distance = 5km + 10km[/tex]
[tex]Total\ Distance = 15km[/tex]
-------------------------------------------------------------------------------------------------------------
Average Speed is then calculated as:
[tex]Average\ Speed = \frac{Total\ Distance}{Total\ Time}[/tex]
[tex]Average\ Speed = \frac{15}{6}[/tex]
[tex]Average\ Speed = 2.5km/hr[/tex]
