Question 1008376
.
At an altitude of 12,250 feet, a hot air balloon springs a leak and begins to be descending at a rate 
of 450 ft per minute. The last opportunity for the crew to safely jump out with a parachute is 1900 feet 
above the ground. How long from the time they Sprung the leak will they have before they are required to jump, 
use an inequality and solve.

        What is offered as an solution in the post by @mananth, is impenetrable nonsense.

        Even do not try to understand what is written there - simply ignore it.

        My correct solution is presented below.



<pre>
As you read the problem, write the inequality for the safety jump

    12250 - 450t >= 1900,


which implies

    t <= {{{(12250-1900)/450}}},

or

    t <= 23 minutes.    <<<---===  <U>ANSWER</U>

Solved correctly.
