Answer:

Step-by-step explanation:

Let Waldo's speed = W

Let Ralph's speed = W + 15

Waldo's distance = speed * Time

Time = 4 hours.

Speed = w

distance = 4 * w

Ralph's speed is W + 15. It's not clear if you need a number. We'll get around to that later.

Ralph traveled 4*(W + 15)

4w + 70 + 4(W + 15) = d

You really can't get a definite answer to these questions. Even if you knew whether they were heading away from each other or towards each other it wouldn't help.
