Question

Ed is on a road trip. He has already traveled 221 miles and is driving at a rate of 61 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 631 total miles?

A.
61x + 221 = 631

B.
61x + 631 = 221

C.
221x + 61 = 631

D.
221x + 631 = 61

Answer 1

A

Explanation:

because 631 is the total miles, the equation will be equal to 631.

Second, because he is driving at 61 miles/hour, 61 will be the rate, so

61x+b=631

sense he already drove 221 miles, that will be where b is, so

61x+221=631
