Question

HELP ASAP OVERDUE TEST!!!!!!!

A scuba diver descends farther down into the ocean from an initial depth of 14.7 feet below sea level. The scuba diver descends at a constant rate for 4 1/2 minutes and reaches a depth no more than 65.1 feet below sea level. What is the maximum rate, r, that the scuba diver may descend?

Answer 1

In minutes: 11.133
In seconds: 0.18555
Explanation:
If he is at 14.7, and he dives for 4 1/2 minutes,
to reach 65.1 (could also be said as O to 50.1)
they should be descending at 11.133 per
minute. 11.133 x 4 is 44.532, and 11.133 x 1/2
is 5.566, and 5.566 + 44.532 = 50.098 (it's
not 50.1, only 50, but it's really close to it so
it's basically 50.1) Also, if it is turned into
seconds, the diver would descend 0.18555 a
second. (11.133 divided by 60 = 0.18555, and
0.18555 x 60 = 11.133) Hope this helps.
