Question

Anaeroplane is flying at a height of 2300 metre if it is sends are constant rate of 15 per minute how long will it take to descend of 300

Answer 1

Step-by-step explanation:

Step-by-step explanation:The height at which the aeroplane is flying=2300

The rate at which the aeroplane is descending=15m

The Height function of aeroplane at any instant of time is given by

The Height function of aeroplane at any instant of time is given byH(t) = 2300-15.t

Now, we need to calculate the time taken by aeroplane to descend at a height of 300

putting h(t)=300

300=2300-15t

300-2300=-15t

-2000=-15t

t=2000/15

t=400/3
