latitude of 35degree north and 70 degree east.30degree north 90degree east.40 degree north 138degree east.

These are three separate locations on earth. You need a world map to locate them.

Is this a LAT/LONG map reading exercise?

35N, 70 E is in the Atlantic Ocean between North Carolina and Bermuda

30N, 90 E is very near New Orleans, LA

40N 138 E is in the Pacific Ocean, about 1000 miles west of Cape Mendocino, northern CA

I read you latitudes as West by mistake. Force of habit.

35N, 70 E is near Kabul, Afghanistan

30N, 90 E is near Lhasa, Tibet, China

40N 138 E is offshore of Akita, Japan in the Sea of Japan.

To find the latitude and longitude coordinates you mentioned, we need to understand the format for representing coordinates.

Latitude measures how far north or south a location is from the equator, and longitude measures how far east or west a location is from the Prime Meridian. The coordinates are given in the format of "(latitude, longitude)" or "latitude° direction, longitude° direction."

Let's break down the coordinates you provided:

1. 35 degrees north, 70 degrees east:
Latitude: 35°N (35 degrees north of the equator)
Longitude: 70°E (70 degrees east of the Prime Meridian)

2. 30 degrees north, 90 degrees east:
Latitude: 30°N
Longitude: 90°E

3. 40 degrees north, 138 degrees east:
Latitude: 40°N
Longitude: 138°E

These coordinates represent different locations on the Earth's surface.
