A passenger ship leaves port sailing east at 14 mph. Two hours later, a cargo ship leaves the same port heading north at 10 mph.

 

(a) Find a function giving the distance in miles between the two ships t hr after the passenger ship leaves port.

D(t)   =  14t   if   0 ≤ t ≤ 2 ,

 

            √ [  (14t )^2  + ( 10t)^2 ]  =  t√ [296 ]  = 2t√74    if  t > 2
