If a soldier can carry a load of 40 kg for 5 km, how much weight can he carry for 10 km if the weight carried is directly proportional to the distance? (2020)
Step 1: Understand that the soldier can carry 40 kg for 5 km.
Step 2: Recognize that if the distance increases, the weight he can carry decreases.
Step 3: Note that the relationship between weight and distance is directly proportional.
Step 4: Since the distance is doubling from 5 km to 10 km, we need to find out how this affects the weight.
Step 5: If the distance doubles (from 5 km to 10 km), the weight he can carry is halved.
Step 6: Calculate the new weight: 40 kg divided by 2 equals 20 kg.
Step 7: Conclude that the soldier can carry 20 kg for 10 km.
Direct Proportionality – The relationship between two quantities where one is a constant multiple of the other, indicating that as one increases, the other decreases in a predictable manner.
