In an hour, the dolphin can go 30-25 = 5 more miles than the sea lion.
So in 5 hours, the dolphin can go 5+%2A+5 or 25 miles farther

Let d%5Bd%5D= the distance the dolphin travels in miles
Let d%5Bs%5D= the distance the sea lion travels in miles
Let r%5Bd%5D= the dophin's speed
Let r%5Bs%5D= the sea lion's speed
Let t%5Bd%5D= elapsed time for the dolphin
Let t%5Bs%5D= elapsed time for the sea lion
---------------------------------------
I can write equations for both animals
d%5Bd%5D+=+r%5Bd%5D%2At%5Bd%5D
and
d%5Bs%5D+=+r%5Bs%5D%2At%5Bs%5D
-----------------------
given:
r%5Bd%5D=+30mi/hr
r%5Bs%5D+=25mi/hr
t%5Bd%5D+=+5hrs
t%5Bs%5D=+5hrs
------------------
Now I can write
d%5Bd%5D+=+30%2A5
d%5Bd%5D+=+150mi
d%5Bs%5D+=+25%2A5
d%5Bs%5D+=+125mi
150+-+125+=+25
The dolpin can swim 25 mi farther than the sea lion in 5 hrs
