a helicopter rose 2400 feet, descended 1650 feet, and then descended another 725 feet. what was the net gain or loss in altitude?

a.
gained 25 ft

b.
lost 750 ft

c.
lost 25 ft

d.
gained 750 ft

The best and most correct answer among the choices provided from your question is the first choice or letter A. gained 25 ft. The solution of the problem is as follows:

Net gain/loss = Height gained + Height lost = 2400 ft + (-(1650ft + 725ft) = 25 ft 

Therefore, the net height gained by the helicopter is 25 ft. 

I hope it has come to your help.
