Miles per hour is velocity so I agree with you. Without seeing any associated question, though, it's hard to say. If the question is, find the average velocity, then velocity is correct. But since change in velocity is negative, that is also negative acceleration.
<span>the one that should be taken as consideration when describing the quality of a sound is: D.The number of the overtones in the sound
Too many overtones indicated that there is too many unrelated sound that make a lot of the sound's part became redundant and unecessary</span>

Oxygen is obtained on a commercial scale through the liquefaction and distillation of ambient air at air separation plants. A secondpurification process may be necessary if ultra-high purity levels are required. High-purity oxygen can also be produced through the electrolysis of water.
Answer:
speed of the spaceship is 0.495251 c
Time T = 1.4982 hr
Explanation:
given data
length L1 = 1600 m
length L2 = 1390 m
to find out
speed of the spaceship and time
solution
we know here
L2 = L1 × 
so we find V by put L1 and L2
1390 = 1600 × 
V = 0.495251 c
speed of the spaceship is 0.495251 c
and
we know T1 = 1.95 hr
so we find T2
T1 = T2 
put here V and T1 so we get T2
1.95 = T2 
Time T = 1.4982 hr
