Ed is on a road trip. he has already traveled 208 miles and is driving at a rate of 70 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 695 total miles?
a.
70x + 208 = 695

b.
208x + 70 = 695

c.
208x + 695 = 70

d.
70x + 695 = 208

If the total distance is 695 miles, and Ed already traveled 208 miles. We also know that Ed is traveling at 70 miles per hour, so in one hour, he travels 70 miles, in two hours he travels  2*70 = 140 miles.

then he need to travel 695 - 208 miles to reach his destination:

if his velocity is 70 mi/h, then you can find x (the number of hours Ed has left in his road trip) by:

70mi/h*x = 695 - 208 or

70x + 208 = 695

So the correct solution is A.

And solving it we get :

70*x = 487

x = 487/70 = 6.95 hours

so Ed has 6,95 hours left in his road trip.
