Question

I don’t understand this problem at all.

Answer 1

The answer is:

D. 5 hours

The equation should be:

(70x) - (20x) = 250

Because we have all the possible answers, we can plug one of them into x to see if it equals 250 miles.

Use an educated guess. I'm going to go with 5 because it seems reasonable.

(70 * 5) - (20 * 5) = 250

Let's check to see if it equals 250:

• 70 * 5 = 350

• 20 * 5 = 100

• 350 - 100 = 250

Therefore, the answer is D. 5 hours.
