Let's break down Aslam's movements:

1. 3 km east

2. 6 km north

3. 5 km east

Total eastward distance = 3 + 5 = 8 km

Aslam's position forms a right-angled triangle with the starting point:

Eastward distance = 8 km (base)

Northward distance = 6 km (height)

Using the Pythagorean theorem to find the distance from the starting point:

distance = √(8² + 6²)

= √(64 + 36)

= √100

= 10 km
