Eric traveled to three cities on a single highway. The distance from his original location to the first city was 100 miles more than the distance from the first city to the second city. The distance from the second city to the third city was 10 miles less than the distance from the first city to the second city. If the distance from his original location to the first city and the distance from the second city to the third city were the same, what was the total distance Eric traveled?

Answer:
Let the distance between the origin and the 1st city =D. =The distance between 2nd and 3rd city. d = 120 miles - distance between 1st and 2nd city. 1/3 x 120 + 100 = 140 miles - distance between origin and 1st city.

Answer: Option E 400 miles
Step-by-step explanation:
280 is the distance traveled from original to 1st city and 2nd and 3rd.
The distance between 2nd and 3rd city is x=120.
Half of 280 is 140
So the total distance is 140+140+120 which is 400 miles
