Ram traveled 3 km east and then took a right turn, which means he traveled south for 4 km. To find the distance between his current location and the starting point, we can use the Pythagorean theorem.

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, Ram's travel can be represented as a right-angled triangle, with one side being 3 km (east) and the other side being 4 km (south). Let's denote the distance he is from the starting point as "d."

Using the Pythagorean theorem:

d^2 = (3 km)^2 + (4 km)^2 d^2 = 9 km^2 + 16 km^2 d^2 = 25 km^2

Taking the square root of both sides:

d = √(25 km^2) d = 5 km

Therefore, Ram is 5 km away from the starting point.
