Question

Zoey is 362 meters below sea level while visiting a part of Israel. She descends 71 meters to visit the Dead Sea.

Which numbers should she use to estimate the depth, in meters, of the Dead Sea?
–400 and –50
–400 and 50
400 and 50
400 and –50

Answer 1

–400 and –50

Reason: -362 ≈ -400 and -71 ≈ -50, so estimate -400 + (-50) = -450 meters (close to the exact -433 m).
