Answer:
16.88 feet per second
Explanation:
We are given;
- The speed of sailboat as 10 nautical miles per hour
We are required to convert the speed into ft per second.
- But we are given, 1 nm = 6076 ft
- We also know that, 1 hour = 3600 seconds
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
