Question 364475
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?
---------------
24 ft/3 sec = 8 ft/sec walking
If she goes the same direction as the boat, the speeds are added.
8 + 5 = 13 ft/sec wrt the land.
