a mountain climbers starts a clown at the elevation of 453 ft above sea level at his first rest stop he has crowned 162 ft by his second rest stop he has clown another $270 ft is getting late in the day so the camera starts its way down the climber describes 285 ft how much does he need to exceed or deceive to return to the original starting point

To determine how much the mountain climber needs to ascend or descend to return to the original starting point, we need to calculate the net displacement.

Net displacement = (Initial elevation + Ascended elevation) - Descended elevation

Initial elevation = 453 ft
Ascended elevation = 162 ft + 270 ft = 432 ft (since the climber has ascended another 270 ft by his second rest stop)
Descended elevation = 285 ft

Net displacement = (453 ft + 432 ft) - 285 ft
Net displacement = 885 ft - 285 ft
Net displacement = 600 ft

The mountain climber needs to ascend or descend by 600 ft to return to the original starting point.
