Answer
d > 2663
Step-by-step explanation
We are told that Rina hasn't reached Base camp,
So, the distance d from the peak will be the distance to base camp plus the distance from base camp to the peak.
Distance from base camp to the peak = 12358 - 9695 = 2663 ft.
So, the distance d will be more than this distance.
d > 2663
Hope this Helps!!!
