5) A rocket sled accelerates along a long, horizontal rail. Starting from rest, two rockets burn for 10s, providing a constant acceleration. One rocket then burns out, halving the acceleration, but the other burns for an additional 5s to boost the sled's speed to 625 m/s. How far has the sled traveled when the second rocket burns out?
