Ocean
(a) Calculate the time T if he walks 1800 feet along the paved path and then 600 feet in the sand to the house.
$\mathrm{T}=8$ minutes
(Type an integer or decimal rounded to one decimal place as needed.)
(b) Calculate the time $T$ if he walks in the sand directly toward the ocean for 600 feet and then turns left and walks along the beach for 1800 feet to the house.
$\mathrm{T}=$ $\square$ minutes
(Type an integer or decimal rounded to one decimal place as needed.)
