Answer 2

Calculation of Chocolate Consumption

To calculate how long the chocolate will last if the child eats one piece every half hour, we need to determine the total number of pieces of chocolate and divide it by the consumption rate.

Given: - The mother left 21 pieces of chocolate. - The child will eat one piece every 30 minutes.

To find the total time the chocolate will last, we need to divide the total number of pieces by the consumption rate:

Total time = Total number of pieces / Consumption rate

Let's calculate it:

Total number of pieces = 21 pieces Consumption rate = 1 piece every 30 minutes

Total time = 21 pieces / 1 piece every 30 minutes

To simplify the calculation, let's convert the consumption rate to hours:

1 hour = 60 minutes

Total time = 21 pieces / 1 piece every 0.5 hours

Now, let's calculate the total time:

Total time = 21 pieces / 0.5 hours

Total time = 42 hours

Therefore, if the child is obedient and eats one piece of chocolate every 30 minutes, the chocolate will last for 42 hours.

Please note that this calculation assumes that the child will not eat any additional chocolate or consume it at a different rate.
