Answer:
x=25
Step-by-step explanation:
First, we add all like terms. Then, we solve for x.
![70+x + 55 + 30 = 180\\x+70 + 55 + 30 = 180\\x+155=180\\x=25](https://tex.z-dn.net/?f=70%2Bx%20%2B%2055%20%2B%2030%20%3D%20180%5C%5Cx%2B70%20%2B%2055%20%2B%2030%20%3D%20180%5C%5Cx%2B155%3D180%5C%5Cx%3D25)
We can rearrange some things because order does not matter with addition. Next, we just use basic equation solving techniques.
Answer: 54.4 mph
Step-by-step explanation:
First find the distance to the train station. If it took Carlos 4 hours to come back driving at 68 mph, the distance is:
= Speed * time
= 68 * 4
= 272 miles
This means that Carlos drove for 5 hours to cover 272 miles the first time. His average speed was therefore:
= Distance / time
= 272/5
= 54.4 mph
