Question

Emily is a driver. If she descended to a depth of 35 ft below sea level then swam 11 ft back towards the surface, where would she be?

a) 24 ft below sea level.
b) 35 ft below sea level.
c) 11 ft below sea level.
d) 11 ft above sea level.

Answer 1

After swimming 11 ft towards the surface from a depth of 35 ft below sea level, Emily would be at a depth of 24 ft below sea level.

Step-by-step explanation:

If Emily descends to a depth of 35 ft below sea level and then swims 11 ft back towards the surface, we need to calculate the difference between her initial and final positions to find out where she would be. We start with her initial depth of -35 ft (since below sea level is considered negative) and then add the 11 ft she swam back towards the surface. This is the same as subtracting the 11 ft from her initial depth:

-35 ft + 11 ft = -24 ft.

In other words, after swimming up 11 ft towards the surface, Emily would be at a depth of 24 ft below sea level.

So, the correct answer is a) 24 ft below sea level.
