Question

Arrange the vehicles in descending order according to the altitudes at which they operate.

Answer 1

According to the given data, the operating altitude of a glider is 5000 ft.  Next highest is that of an airship, at 3000 ft.  Next is a sailboat (water level, or 0 ft).
Last is a submarine, 1500 feet below the surface.

{5000, 3000, 0, -1500} (answer)

Answer 2

Answer:

D.Glider ,airship,sailboat,submarine

Step-by-step explanation:

We are given that

Vehicle              Sailboat     submarine      glider    Airship

Altitude (feet)        0               -1500             5000     3000

We have to arrange the vehicles in descending order according to altitude at which they operate.

Descending order: It is that order in which largest number comes first and smallest number comes last.We go from highest to lowest in this order.

Therefore, 5000 comes first and -1500 comes last because 5000 is largest number and -1500 is smallest number in given numbers.Altitude of glider is largest and altitude of submarine is smallest.
