Answer:
The elevation of Death Valley = 31/160 feet
Step-by-step explanation: Since
The lowest elevation in Long Beach, California, is 7 ¾ feet
Let say L = 7 ¾ feet
The elevation of Death Valley is about 40 times lower than the elevation of Long Beach
That is D = 1/40 of L
D = 1/40 × 31/4
D = 31/160 feet
The elevation of Death Valley is 31/160 feet
