Answer:
1,080 ft
Step-by-step explanation:
Rate of descending or travel (r) = 18 ft per second.
The depth or distance traveled/descended (d) after 1 minute can be calculated as follows:
[tex] d = r*t [/tex]
r = 18ft/sec
t = 1 min = 60 secs
[tex] d = \frac{18 ft}{1 sec}*60secs [/tex]
[tex] d = 18ft*60 [/tex]
[tex] d = 1,080 ft [/tex]
