An increase in railroad mileage in an area led to great economic growth in that area. Between 1870 and 1890, which area had the greatest increase in railroads and, as a result, the most significant economic growth?

A. New England
B. The South
C. Western states and territories
D. The middle states



Answer :

To determine which area had the greatest increase in railroad mileage between 1870 and 1890, follow these steps:

1. Identify the railroad mileage for each area in 1870 and 1890:
- New England: 2,507 miles in 1870 and 6,831 miles in 1890.
- Middle States: 3,202 miles in 1870 and 21,536 miles in 1890.
- Southern States: 2,036 miles in 1870 and 29,209 miles in 1890.
- Western States: 1,276 miles in 1870 and 62,394 miles in 1890.

2. Calculate the increase in railroad mileage for each area:
- New England:
- Increase = 6,831 - 2,507 = 4,324 miles
- Middle States:
- Increase = 21,536 - 3,202 = 18,334 miles
- Southern States:
- Increase = 29,209 - 2,036 = 27,173 miles
- Western States:
- Increase = 62,394 - 1,276 = 61,118 miles

3. Compare the increases to find the maximum:
- New England: 4,324 miles
- Middle States: 18,334 miles
- Southern States: 27,173 miles
- Western States: 61,118 miles

The Western States had the greatest increase, with an additional 61,118 miles of railroad by 1890.

Therefore, the Western states and territories experienced the most significant economic growth due to the greatest increase in railroads between 1870 and 1890.
