Answer:
5.85 kilograms
Explanation:
We are told that Three hikers started climbing with each hiker carrying 7.8 kilograms of weight.
Thus, total weight carried by them = 7.8 × 3 = 23.4 kilograms
Now a fourth person joined them and they divided the weight equally.
Thus, each hiker will now carry;
23.4/4 = 5.85 kilograms
