Question

Ed is on a road trip. He has already traveled 209 miles and is driving at a rate of 67 miles per hour. Which equation could be used to find how many hours, x, Ed has left in his road trip if he is traveling 611 total miles?

Answer 1

611 miles = 209 + 67x

611 miles total
209 driven

67(x)
where x how many hours he has left

Answer 2

And algebraically,

611 = 209 +67x

subtract 209 from both sides to isolate x

becomes

402 = 67x
divide both sides by 67

6 = x
