Question

A traffic helicopter descends to hover 477 meters above the ground. Let h be the original height of the helicopter. What is a subtraction equation that represents the problem? What was the original height of the helicopter?

Answer 1

The subtraction equation that represents the problem is ( h-477)metres

Subtraction problem

Given the following information

• The original height of the helicopter = h meters

If the traffic helicopter descends to hover 477 meters above the ground, then the original height of the helicopter will be:

Original height = h - 477 (Since it is descending)

Hence the subtraction equation that represents the problem is ( h-477) meters
