+d+=+r%2At+
The boat's rate is +336%2F7+ mi/hr
+144+=+%28+336%2F7%29%2At+
+t+=+144%2A%28+7%2F336+%29+
+t+=+3+ hrs
---------------
Note that the units are miles/hr and miles,
so you don't have to convert any units.

A boat travels 336 miles in 7 hours(with constant speed). How much time will it take to travel 144 miles?
-------
Use a proportion:
time/distance = time/distance
---
x/144 = 7/336
-----
x = (144)(7/336)
x = 3 hrs
