A 40-cm spring will stretch (in cm) one third the weight (in kg) attached to it. How long will the spring be if a 15-kg weight is attached?

Answer: 45cm

Step-by-step explanation:

The spring stretches 1/3 of the weight attached. 1/3 of 15 is 5. However, the spring is already 40cm long so we must add 5 to 40 to find the total length and of the spring.
