To determine the distance from the starting point, we can visualize the movement of Ram as a right-angled triangle, where the initial 3 km east represents the base of the triangle and the subsequent 4 km represents the perpendicular side.
Using the Pythagorean theorem, we can find the hypotenuse of the triangle, which represents the distance from the starting point:
Hypotenuse² = Base² + Perpendicular²
Hypotenuse² = (3 km)² + (4 km)²
Hypotenuse² = 9 km² + 16 km²
Hypotenuse² = 25 km²
Taking the square root of both sides:
Hypotenuse = √(25 km²)
Hypotenuse = 5 km
Therefore, Ram is 5 km away from the starting point.
