If the Date Trail is 4.5 miles long, the total number of miles that the second group will hike is: C. 14 1/4 miles.
In Mathematics and Physics, distance is the amount of ground that is travelled by a physical object or body over a particular period of time and speed, irrespective of its direction, starting point or ending point.
Based on the table showing the lengths of several trails in a national park, the total distance hiked by the second group of friends can be calculated as follows;
Alpine Trail (1 time) = 2 3/4 miles.
Cedar Trail (2 times) = 1 1/4 mile.
Date Trail (2 times) = 4.5 miles
Total distance = 2 3/4 + (1 1/4 + 1 1/4) + (4.5 + 4.5)
Total distance = 11/4 + 5/4 + 5/4 + 9/2 + 9/2
Total distance = 11/4 + 10/4 + 9
Total distance = 14 1/4 miles.
