A deep-sea exploring ship is pulling up a diver at the rate of 25 feet per
minute. The diver is 200 feet below sea level. How deep was the diver
10 minutes ago?
Answers
Answer:
450
Step-by-step explanation:
Since tge diver is being pulled up, measuring his movement for the past
10
minutes requires that we use
−
25
for the movement over those
10
minutes. So, his depth
10
minutes ago is given by the expression
−
200
−
25
(
10
)
−
200
−
250
−
450
So,
10
minutes ago, the diver was
450
feet below sea level.
Answer:
450 ft
Step-by-step explanation:
ok so,
rate at which diver is being pulled up= 25 ft/ min
level at which he is right now= 200 ft below sea level
level he was at 10 mins ago = ?
distance travelled in:
1 min= 25 ft
10 min= 25 x 10 = 250 ft
level at which he was 10 mins ago = level at which he is at right now + distance travelled in 10 mins
=> (200 + 250)ft = 450 ft
∴ level at which diver was at 10 min ago = 450 ft below sea level
if you have any doubt please ask. Hope this explains your question. :)
