Question 179027
Let {{{d[d]}}}= the distance the dolphin travels in miles
Let {{{d[s]}}}= the distance the sea lion travels in miles
Let {{{r[d]}}}= the dophin's speed
Let {{{r[s]}}}= the sea lion's speed
Let {{{t[d]}}}= elapsed time for the dolphin
Let {{{t[s]}}}= elapsed time for the sea lion
---------------------------------------
I can write equations for both animals
{{{d[d] = r[d]*t[d]}}}
and
{{{d[s] = r[s]*t[s]}}}
-----------------------
given:
{{{r[d]= 30}}}mi/hr
{{{r[s] =25}}}mi/hr
{{{t[d] = 5}}}hrs
{{{t[s]= 5}}}hrs
------------------
Now I can write
{{{d[d] = 30*5}}}
{{{d[d] = 150}}}mi
{{{d[s] = 25*5}}}
{{{d[s] = 125}}}mi
{{{150 - 125 = 25}}}
The dolpin can swim 25 mi farther than the sea lion in 5 hrs
