A PLANE IS FLYING AT 30,000 FEET AND NEEDS TO RISE TO 36,000 FEET IN 2 STAGES.
IN STAGE 1, IT RISES 5% OF ITS INITIAL ALTITUDE OF 30,000 FEET..
IN STAGE 2, IT RISES AT A RATE OF 140 FEET PER MINUTE. HOW MANY MINUTES DOES IT TAKE FOR THE PLANE TO RISE TO 36,000 FEET IN STAGE 2

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).
