Final answer:
It will take the comet 10 million days to reach Earth, which is calculated by dividing the distance (10¹² miles) by the speed (10µ miles per day).
Step-by-step explanation:
To calculate how many days it would take a comet that is 10¹² miles away from Earth and traveling at a speed of 10µ miles per day to reach Earth, we can apply a simple division.
First, we take the distance (10¹² miles) and divide it by the speed (10µ miles per day)
10¹² miles ÷ 10µ miles per day = 10⁷ days
Calculating this provides the exact number of days it will take for the comet to reach Earth, which is 10 million days. It is important to note that this is a simplified calculation and in real scenarios, the trajectory and speed can be affected by various factors like gravitational pull and changes in velocity.
