Answer:
h = 9530 m
Step-by-step explanation:
Given that,
A hike starts at an elevation 30 meters below sea level and ends at a point 9500 meters higher than starting point.
We need to find the height at the end of the hike. It can be calculated as follows :
h = 9500 -(-30)
= 9530 m
Hence, he will be at a height if 9530 m at the end of the hike.
