If the plane's speed would have been 1/2 of the actual speed and the ship's speed 1/4 greater than the actual speed, a distance of 1315 miles would have been travelled. Find the speeds of the plane and the ship.

You can put this solution on YOUR website!
rate*time=distance ... p equals plane speed, s equals ship speed ... 4p+25s=1580 ... 4(p/2)+25(s(5/4))=1315\r
