If a soldier can carry a load of 40 kg for 10 km, how much weight can he carry for 5 km at the same rate? (2020)
Step 1: Understand that the soldier can carry 40 kg for 10 km.
Step 2: Recognize that the weight he can carry is proportional to the distance he travels.
Step 3: Since he can carry 40 kg for 10 km, we need to find out how much he can carry for 5 km.
Step 4: Calculate the ratio of the distances: 5 km is half of 10 km.
Step 5: Since the distance is halved, the weight he can carry will also be halved.
Step 6: Divide the original weight by 2: 40 kg / 2 = 20 kg.
Step 7: Conclude that the soldier can carry 20 kg for 5 km.
Proportionality – The relationship between the weight a soldier can carry and the distance he can travel, indicating that if the distance is halved, the weight he can carry is also halved.
