Well, you seem to have left out the units on Val's speed but it doesn't matter. The setup is the same.
distance=velocity*time
So you multiply Val's speed times the time she was running to get the distance she traveled. Then to find the speed Anna must run simply divide Val's distance by the time Anna has to make the trip.
Anna's Velocity = Val's Distance/ Anna's Time
Hope this helps!
