To calculate the distance traveled between two coordinates, you can use the Haversine formula. The Haversine formula calculates the great-circle distance between two points on a sphere given their longitudes and latitudes.

In this case, you want to find the distance traveled from 0 degrees latitude, 0 degrees longitude to 30 degrees north latitude, 120 degrees west longitude.

Here's how you can calculate the distance:

1. Convert the latitude and longitude values from degrees to radians. The Haversine formula works with radians, so we need to convert the values. To convert degrees to radians, use the formula: radians = degrees * (π/180).

For the first point (0 degrees latitude, 0 degrees longitude):
lat1 = 0 * (π/180) = 0 radians
lon1 = 0 * (π/180) = 0 radians

For the second point (30 degrees latitude, 120 degrees west longitude):
lat2 = 30 * (π/180) = π/6 radians
lon2 = -120 * (π/180) = -2π/3 radians

2. Calculate the differences in latitudes and longitudes:
dlat = lat2 - lat1 = π/6 - 0 = π/6 radians
dlon = lon2 - lon1 = -2π/3 - 0 = -2π/3 radians

3. Use the Haversine formula to calculate the distance:
a = sin²(dlat/2) + cos(lat1) * cos(lat2) * sin²(dlon/2)
c = 2 * atan2(sqrt(a), sqrt(1-a))
d = R * c

Where R is the radius of the Earth (approximately 6,371 kilometers or 3,959 miles).

Using the Haversine formula, you can calculate the distance between the two points.
