The average speed of jogger during the journey is 6.4 km/hr.
Given data:
The distance travelled by the Jogger is, d = 8.0 km.
Time taken by the jogger to cover the distance is, t = 1.25 hours.
The average speed of an object is defined as the distance covered by the object in a unit time. Mathematically, it is calculated by dividing the distance travelled and the time interval.
Therefore the expression is,
\(v = \dfrac{d}{t}\)
Here, v is the average speed of jogger.
Solving as,
\(v = \dfrac{8}{1.25}\\\\v=6.4 \;\rm km/hr\)
Thus, the average speed of jogger during the journey is 6.4 km/hr.
