Answer:
16.88 feet per second
Step-by-step explanation:
We are given;
We are required to convert the speed into ft per second.
Therefore;
10 nm = (10 nm × 6076 ft/nm)
= 60760 ft
1 hour = 3600 secs
Therefore;
Speed in ft per sec = 60760 ft ÷ 3600 secs
= 16.88 ft per second
Thus, the speed of the sailboat is 16.88 feet per second
