To find the total number of miles walked by Groups A, B, and C, we need to add up the distances walked by each group.
Group A walked 15 miles.
Group B walked 18 miles.
Group C walked 142 miles.
To find the total distance walked, we simply add these three values together:
15 miles + 18 miles + 142 miles = 175 miles.
Therefore, the total number of miles walked by Groups A, B, and C is 175 miles.
