I have a really hard time understanding word problems when it comes to math so can anyone help with these?

1.The sonar operator on a submarine detects an old World War II submarine net and must decide to detour over or under the net. The computer gives the operator a depth model of |d-394|-20>164, where d is the depth in feet that represents safe passage. At what depths should the submarine travel to avoid the net?

2. The Gare Montparnasse train station in Paris has a high-speed version of a moving walkway. If you walk while riding this walkway, you can travel 200 meters in 30 seconds less than if you stand still on the moving walkway. If you walk at a normal rate of 1.5 meters per second, wat is the speed of the Gare Montparnasse walkway?

Any help at all would be greatly appreciated! Thank you!!!
