Answer:
1km/h (ans)
Explanation:
this is because 3km/h means that he travels 3km in 1hour if he add 1km/h in his speed then his speed will be 4km/h which means that he travels 4km in 1hour or 2km in 30 minutes and the distance is 2km and he had to reach in 30 minutes so he will perfectly reach on time. Hope It Helps
