Expert Answer
Old position = -300 feet below sea level
Ascend in position = 900 feet
Change in position is given by -300 + 900.
To find this, start with -300 and move 9 steps to the right as the gap between steps is 100.
After moving, we reach at 600, so -300 + 900 = 600 feet
Joshua is 600 feet above sea level.
Ascend in position = 900 feet
Change in position is given by -300 + 900.
To find this, start with -300 and move 9 steps to the right as the gap between steps is 100.
After moving, we reach at 600, so -300 + 900 = 600 feet
Joshua is 600 feet above sea level.
