Question

"The maximum capacity of an elevator is 600 kg. How many adults, weighing 80 kg, can enter the elevator if there is already a boy weighing 40 kg in the elevator?

a) 6 adults
b) 5 adults
c) 4 adults
d) 3 adults"

Answer 1

The elevator can fit 7 adults after the boy enters.

Step-by-step explanation:

To find the number of adults that can enter the elevator, we need to calculate the remaining weight capacity of the elevator after the boy enters. The weight of the boy is 40 kg, and the weight of each adult is 80 kg. Since the maximum capacity of the elevator is 600 kg, we can subtract the weight of the boy from the maximum capacity and divide the result by the weight of each adult.

(600 kg - 40 kg) / 80 kg = 7 adults

So, the elevator can still fit 7 adults after the boy enters.
