Answer:
The Great Western Trail = 4,455 miles
Step-by-step explanation:
The Iditarod Trail = 1,025 miles long
The Great Western Trail is 355 miles longer than 4 times the length of the Iditarod Trail.
The Great Western Trail = (4 × 1,025) miles + 355 miles
= 4,100 miles + 355 miles
= 4,455 miles
The Great Western Trail = 4,455 miles
