Question

A helicopter is flying at a altitude of 785 feet.It descends 570 feet, and then ascends 595 feet.

Answer 1

Answer:

810 feet.

Step-by-step explanation:

We are supposed to find the final altitude of the helicopter.

We have been given that a helicopter is flying at a altitude of 785 feet, this means that altitude of helicopter is positive.

Further, the helicopter descends 570 feet, this means that altitude of helicopter is $-570$.

Finally, the helicopter ascends 595 feet, this means that altitude of helicopter is $595$.

$\text{Helicopter's final elevation}=785\text{ ft}-570\text{ ft}+595\text{ ft}$

$\text{Helicopter's final elevation}=810\text{ ft}$

Therefore, the final elevation of helicopter is 810 feet.

Answer 2

785-570= 215 + 595 =810
