Answer:
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.
