Question 1054442
You planned a trip with your best friend from college. You had only 4 days for your trip and planned to travel x hours each day.
The first​ day, you stopped for sightseeing and lost 3 hours of travel time 
x-3 hrs 
The second​ day, you gained 1 hour because you did not stop for lunch.
x+1 hrs 
The third​ day, you traveled well into the night and doubled your planned travel time.
2x hrs
The fourth​ day, you traveled only a fourth of the time you planned because your friend was sick.
x/4 hrs 
-----------------------------
You averaged 50 miles per hour for the first 2 days and 56 miles per hour for the last 2 days. Complete parts a through f.
---------------------------------------- 
a. How many​ hours, in terms of​ x, did you travel the first 2​ days?
2x-2 hr 
b. How many​ hours, in terms of​ x, did you travel the last 2​ days?
2.25x 
c. Express the total​ distance, D, traveled over the 4 days as a symbolic rule in terms of x.
D=226x-100 
d. Write a symbolic rule that expresses the total​ distance, y, you would have traveled had you traveled exactly x hours each day at the average speeds indicated above.
y= 50(2x)+56(2x) mi  = (50+56)2x = (106)*2x = 212x
