Question

Ed is on a road trip. He has already traveled 238 miles and is driving at a rate of 68 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 615 total miles?

Answer 1

Answer:

x = (615 - 238) / 68

Step-by-step explanation:

Answer 2

Answer:

615 = 68x + 238

Step-by-step explanation:

You have to set the equation equal total miles and to find the time you multiply the amount of remaining hours (x) by the miles per hour and then add the miles already traveled. To find the value of x do simple algebra and isolate x on one side of the equation by subtracting 238 from both sides and then dividing both sides by 68.
