Question

A small plane is flying at 150 feet. It ascends to 325 feet. Write and solve an equation to find the change in altitude of the small plane.

Answer 1

Answer:

  175 ft

Step-by-step explanation:

Let c represent the change in altitude. Then an equation can be written:

  150 +c = 325

We solve for c by subtracting 150 from both sides of the equation:

  c = 325 -150 = 175

The change in altitude is an increase of 175 feet.

_____

This confirms the general rule that to find the value of a change, you subtract the original value from the new value. Here, that means ...

  c = 325 -150 = 175 . . . . as above.
