The amount of water in a container doubles
every minute. After 6 minutes, the container
is full. Your friend said it was full after 3
minutes. Is your friend correct? If yes,
explain why. If no, provide the correct
answer.
What is…
“No”
The friend is incorrect. The amount of
water doubles every minute, so it is full
1 minute after the container is halfway full. It is full after 6 minutes,
therefore it was half-way full at 5
minutes.
