please help me set up this equation.
A person traveling 4 hr by plane and 25hr by ship covers 1580 miles. If the speed of the plane had been one-half of the actual speed and the speed of the ship had been one-forth greater, the person would have traveled only 1315 miles in the same length of time. Find the speeds of the plane, and the ship.

4 p +25 s = 1580
4(p/2) + 25(p+ p/4)=1315

If you solve the 2 equations, you get that the speed of the plane is less than the speed of the ship. Are you sure of the wording of the problrm?
