What path was a pedestrian moving with an average ground speed = 4.8 km / h during a period of time t = 0.5 h.

These tasks: V (average ground speed of the considered pedestrian) = 4.8 km / h; t (pedestrian travel time) = 0.5 h.
The path that the pedestrian had to cover in 0.5 hours is calculated using the formula: S = V * t.
Let’s perform the calculation: S = 4.8 * 0.5 = 2.4 km.
Answer: In 0.5 hours, the pedestrian in question covered 2.4 km.
