a. -8/3 miles below sea level.
Sasha started at sea level and has hiked down to the fourth rest station.
Now sea level is 0.
Sasha takes a break at the rest stations every 2/3 of a mile.
This means she is down to 4 rest points means 4 times 2/3
This becomes =
But the answer will be in negative as she is below 0.
So, correct answer is: a. -8/3 miles below sea level.
Other way,
sea level is 0.....so if u go below sea level, u will end up with a negative number...and since she is hiking down, ur answer will be negative. The is a station every 2/3 mile....and if she passed 4 of them....
-2/3 * 4 = - 8/3 <=== her elevation....another answer could have been - 2 2/3, but that is not there
