What is the formula for an eastbound car is going 4 miles per hour faster than a westbound car. the cars are 208 miles apart 2 h
ivanzaharov [21]
Draw a diagram to illustrate the problem as shown below.

Let v = speed of the westbound car, mph

Because the eastbound car travels 4 mph faster than the westbound car, its speed is (v+4) mph.

After 2 hours,
the westbound car travels 2v miles west, and the eastbound car travels 2(v+4) miles east.
Because they become separated by 208 miles, therefore
2v + 2(v+4) = 208
4v + 8 = 208
4v = 200
v = 50 mph

The westbound car travels at 50 mph.
The eastbound car travels at v+4 = 54 mph

Answer: The eastbound car travels at 54 mph.

Please help. I am not good with this
aniked [119]

Answer:

X= 7

Z= 117

Step-by-step explanation:

Z would be 117 because on the bottom half of the equation it has to be equal to 180. It gave you 63 already and so I just took the 180 and subtracted the 63 to get 117.
