Alyssa's average speed on the round trip is 540 Mies per hour.
We have given,
The speed of the jet Alyssa flew on from Boston to London was 480
mph.
On her return flight, the speed of the jet was 600 mph with a tail
wind.
<h3>What is the average speed?</h3>

a=inital speed
b=final speed
add 600 and 480 then divide by 2
That can be given by

Answer:
We readily separate the variables and integrate:
∫dP/P=∫(k+bcos2
t)dt
ln P=kt+(b/2
)*sin2
t+ln C
Clearly C = Po, so we find that P(t) = Poexp(kt + (b/2
)* sin 2
t). The 271- curve with the typical numerical values P_o = 100, k = 0.03, and b = 0.06. It oscillates about the curve which represents natural growth with P_o and k = 0.03. We see that the two agree at the end of each full year.

Answer: 7/(2x+3^2)
Step-by-step explanation:
y=mx+b
y=7
mx=2x
+b =3^2
7 ÷ ( 2x + 3²)
Answer:
C=8
