Answer: Raina's distance from the mountains is 176 miles
Step-by-step explanation:
Let x represent her average rate on the trip to the mountains.
If her average rate was 22 miles per hour faster on the trip home, it means that her average rate on the trip home is (x + 22) mph
Distance = speed × time
There was heavy traffic on the way there, and the trip took 6 hours. This means that the distance on her way to the mountain is 6x
When Raina drove home, there was no traffic and the trip only took 4 hours. This means that the distance on her way to home is
4(x + 22)
Since the distance covered is the same, then
6x = 4(x + 22) = 4x + 88
6x - 4x = 88
2x = 88
x = 88/2
x = 44
Raina's distance from the mountains is
6 × 44 = 176 miles
B the plane has only one dimension
Answer:
13.5
Step-by-step explanation:
There is no constant of proportionality.
Step-by-step explanation:
So if you were to take 2 points, let's say (4,5) and (8,9). It always has to be y over x, so the fractions will be 5/4 = 9/8. There is a covariance in the denominators of times 2. It's not the same in the numerators.
