Final answer:
Without the rate of descent, we cannot determine how deep Mr. mole was after 6 minutes. Given a hypothetical rate of descent, we can calculate the depth.
Step-by-step explanation:
To calculate how deep Mr. mole was after 6 minutes of digging deeper than his original position 7 meters below ground, we would need additional information such as the rate at which he was descending.
Without that information, we cannot provide a specific numeric answer. If we were given, for example, that he digs 1 meter deeper every minute, then after 6 minutes, he would be 13 meters below the ground.
