A submarine 58 feet below see level. An a airplane is 264 feet above sea level. How far above is the submarine in the plane?​

322

Step-by-step explanation:

58+264=322

322 feet

Step-by-step explanation:

if the question was two positive heights, you would subtract, and you still do. we find how many inches my father is taller than me by subtracting my height from his, and the same applies to this, though the submarine, being below sea level is at a negative height. when you subtract a negative, it's the same as adding a positive.

264 - (-58)          

264 + 58 = 322

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

x=6 and x=3
