An unmanned ocean vehicle named Nereus traveled 35,768 feet below the surface of the ocean. Another vehicle traveled 17,652 feet
below the surface. About how much farther below the ocean’s surface did Nereus travel than the other vehicle?
Round each number to the nearest thousand.
At first I thought it was C but it said to the nearest thousand and I got 18,116 so the nearest THOUSAND is 18,000 so the answer is B...hope this helps
