Looking at the diagram, you can see AB is parallel to DC. You need to use the ratios given to find the distance of DC.

Also it’s worth noting that your answer of (3/5)p is not possible because AB is shorter than DC so DC should be greater than p. Your answer of (3/5)p shows that DC is 0.6 times the size of AB!

Can you explain what the ratio means in terms of the lengths of AB and DC?

That may help you greatly.
