Answer: 199.5 ft
Step-by-step explanation:
Given: A scientist was in a submarine below sea level studying ocean life over the next 10 minutes she went down 58 ft.
If she was 141.5 ft below sea level after she went down , then she had been (141.5 ft + 58 ft) = 199.5 ft below sea level.
Hence, If she was 141.5 ft below sea level after she went down , then she had been 199.5 ft below sea level.
