Atraffic helicopter descends 123 meters to be 309 meters above the ground, as illustrated in the diagram to the right. write an equation to describe the situation using h as the original height of the helicopter. what was the original height of the helicopter?
write an equation to describe the situation using h as the original height of the helicopter.

the original height of the helicopter=432 meters ;  h-123=309

Step-by-step explanation:

the original height of the helicopter = h       [Given]

now,

helicopter descends 123 meters

so, h-123

to be 309 meters above the ground

so, h-123=309

=>h=309+123

=>h=432

this doesn't make sense lol

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
