Question

Jack’s school is 20 miles from his house. He has already traveled 13 miles. If d represents the distance he still needs to travel to reach his school, write an equation to represent this situation. Then use this equation to find the distance Jack still needs to travel to reach his destination.

Answer 1

20 - 13 = D or 13 + D = 20

Explanation:

The words in the word problems give hints on how to write this equation with an unknown number. Like "...already traveled 13 miles." I honestly do not know how to explain it better but I hope this helps
