⇒ 
Gather like terms and combine:
⇒ 
⇒ 
Add 14 to each side of the equation:

You can’t really show work for this problem, but the answer is A. This is because physics is about motion, energy, force and stuff and when you get in to a wreck, there are forces and stuff lol
2 miles and 20 yards is equal to 3,540 yards.
This is a very good question to know about. People who make tests really like it.
The way to solve it is to make the slower car stop and use the difference in speed = to the rate. then do it as an ordinary d = r*t problem.
The difference in speeds is 44 - 36 = 8 miles/ hour.
d = 260 miles
r = 8 mph
t = ???
t = d/r
t = 260/8
t = 32.5 hours.
Thats 32 1/2 hours.
