Answer :
Answer:
v=0.15 miles per second
Step-by-step explanation:
The distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15t.
We need to find how fast is it flying.
Differentiate the given equation wrt t.
[tex]\dfrac{dd}{dt}=\dfrac{d}{dt}(0.15t)\\\\\because \dfrac{dd}{dt}=\text{velocity(v)}\\\\v=0.15[/tex]
It means the velocity of the airplane is 0.15 miles per second.
