Answer:
45 minutes
Step-by-step explanation:
The aeroplane is flying at a height of 2100m
It has to descend to a height of 300m
therefore, the height through which the aeroplane has to descend = 2100-300 = 1800
no we use the formula for finding Time
T= S/V
where T is time, S is distance travelled and V is velocity/speed
T=1800/40
therefore, T = 45 minutes
