Answer: $12 + 40d\geq 100$

Step-by-step explanation:

Since, the miles john have cover = 12 miles.

And, the remaining days he has = 40

If d is the average miles he cover in these 40 days.

Then, the total miles he cover in 40 days= 40 d

Thus, the total miles he cover in this summer = 12 + 40 d

According to the question,

He has a goal of covering at least 100 miles in this summer.

That is, the total miles he cover in this summer ≥ 100

⇒ 12 + 40 d ≥ 100

Which is the required inequality.
