The return trip was 21.2 hours long.
Step-by-step explanation:
Given,
Speed of plane from US = 212 mph
Speed of plane on return trip = 232 mph
Let,
x be the time taken on return trip.
Time taken from US = x+2
We know that;
Distance = Speed * Time
Distance of plane from US = 212(x+2) = 212x+424
Distance on return trip = 232x
As the distance will be same, therefore,
Dividing both sides by 20
The return trip was 21.2 hours long.

Answer:
The equation shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A, in astronomical units, AU. If planet Y is twice the mean distance from the sun as planet X, by what factor is the orbital period increased?
Step-by-step explanation:
Answer:
1) 6(3x-2)
2) 24(x+2)
3) 9(5x−9) or 9(5x+9) if you meant to put addition.
4)8x+15
Answer:
14 weeks.
Step-by-step explanation:
15x-10=200
add 10 to both sides
15x= 210
divide by 15
x=14 .
