If you started at the prime meridian on the equator and traveled 690 miles to the east and then turned around and traveled 207 miles to the west at what line of longitude would you be?

The correct answer is 90-degree East longitude

Explanation:

Let us recall from the questions given as:

From the east you travel about = 690 miles

From the west you travel about = 207 miles,

We solve for the line of longitude,

At an angle of zero degrees The prime meridian begins, and the total degrees is 360, and when divided it gives you 180 degrees on the east and west respectively.

Then.

The longitude of number given is of 90 degrees.

Therefore, if you travel to the direction east away from prime meridian we have the value of 90-degree East longitude.

If I started at the prime meridian on the equator and traveled 690 miles to the east, then turned around and traveled 207 miles to the west than the line of longitude will be 90 degrees East.

Explanation:

Prime meridian starts off at an angle of zero degrees, and there being total of 360 degrees, which gets divided into 180 degrees on west and east.

Then the number formed will be of 90 degrees.

S if travels or moved to east direction away from prime meridian we get the value of 90-degree East longitude.
