Answer:
The average speed of the trip there is <u>86 mph.</u>
Step-by-step explanation:
Given:
Time taken to reach Portland = 3 hours
Time taken to come beck from Portland = 6 hours
Average speed for the returning trip = 43 mph
Distance traveled for the returning trip can be obtained by multiplying the returning speed by returning time. Therefore, distance for returning trip is:
Now, distance traveled for the return trip is same as going to the trip.
So, distance traveled by Jessica going to Portland = 258 miles.
Time taken to go there = 3 hours
Therefore, speed of the trip there is given as the ratio of distance and time and is given as:
Therefore, the average speed of Jessica's car to go to Portland is 86 mph.

Aaron is 4 years and Maria is 14 years old.
A = Aaron's age today
M = Maria's age today.
a. The equation based on the statement given will be:
M = A + 10
b. Maria's age based on the statement in 6 years will be:
= (A + 10) + 6
= A + 16
c. Based on the information above, the equation to solve their ages will be:
A + 16 = 2(A + 6)
A + 16 = 2A + 12
Collect like terms
2A - A = 16 - 12
A = 4
Therefore, Aaron is 4 and Maria is 14 years.

To find the length of the light pole you'll have to use the sine ratio.
sin 30 = x/43
43 (sin 30) = x
21.5 = x
Hope this helps :)
A. Its a square. This means each side times the side would give us the area (s^2)
4/3^2 or 1.3333 x 1.33333 = 16 / 9 area.
B. Really just pick any numbers you want.
16 yards long and 1/9 wide.
As long as they multiply to 16/9
