Question

A traffic helicopter descends 114 meters to be 454 meters above ground, as illustrated in the diagram to the right. Write an equation to describe the situation using h as the original height of the helicopter. What was the original height of the helicopter?

Answer 1

H = h + x

h = 568 meters

Explanation:

The helicopter descends 114 meters to be 454 meters above the ground.

Therefore, the equation which describes this situation using h as the original height will be given by

H = h + x ....... (1)

Where H is the final height from the ground and x is the height that the helicopter ascends(Positive sign) or descends(Negative sign). (Answer)

Here, in our case, H = 454 meters and x = -114 meters.

Therefore, the original height of the helicopter from ground will be

h = H - x = 454 - (-114) = 568 meters. (Answer)
