The average weight per adult is 150 pounds, and the average weight per child is 40 pounds . The maximum weight is 1,500 pounds. Suppose there are ten children in the elevator how many adults can get in.
2 answers:
With the ten children already in the elevator, the weight is at 400 pounds. Therefore you have 1,100 pounds before reaching the maximum weight. So about 7 adults can get in.
If the lift can have 1,500pounds you will have to subtract the children first.
