<PRE><B>Question 405481</B>
 In 3 sec, Penny walks 24 ft, to the bow (front) of a tugboat. The boat is cruising at a rate of 5 ft/sec. What is Penny’s rate of travel with respect to land?
----
Equation:
rate + rate = total rate
(24 ft/3 sec) + 5 ft/sec 
= 8ft/sec+5 ft/sec 
= 13 ft/sec
=====================
