Answer:
The length of the entire bicycle trail = 22.52 kilometers
Explanation:
A bicycle trail consists of a mountainous part and a flat part.
Total number of parts = 2
The mountainous part of the trail is 5.92 kilometers long, and the flat part of the trail is 16.6 kilometers long
Total length of mountainous part of the trail = 5.92 kilometers
Total length of flat part of the trail = 16.6 kilometers
Total length of part 1 = 5.92 kilometers
Total length of part 2 = 16.6 kilometers
The length of the entire bicycle trail = Total length of part 1 + Total length of part 2
The length of the entire bicycle trail = 5.92 + 16.6 = 22.52 kilometers
