Rational function problem (please help)

[f---s]

The maximum time, T, in minutes a scuba diver without stopping for decompression on the way up the surface is defined by the T(d) =525/d-10 with d>10, where d is the depth of the dive, in meters. For the maximum time to be less than 30 minutes, how deep can the diver dive ?

a) Solution with conclusion
b) State the asymptotes and their meaning in context of the problem

1) 525/d-10 is NOT the same as 525/(d-10)
2) Why, do you suppose, the problem statement bothered to mention "d > 10"?

Please help me solve this, it is very confusing for me, I know d>10 and maximum time should be less than 30 min.

And it is (d-10) but d-10 in the denominator

Not a good answer. I sent you a plea to show your own work. I guess you're not going to do that?

d > 10
T < 30
b) State the asymptotes and their meaning in context of the problem

Have you considered solving T = 30? What value of d results?

You must interpret the results and make conclusions. It's not a solve and move on osrt of problem statement.

d value is 27.5m at point (27.5, 30)

So how deep can the diver dive?
