Question

An aeroplane was flying at a height of 1800 m. If it descends at a constant rate
of 60 m per minute, how long will it take to descend to a height of 300 m?​

Answer 1

Answer:

height = 1800 m

descent rate = 60 m/min

it has to come down a distance of (1800-300)= 1500m

time =1500÷60=25 min
