#### An aeroplane was flying at a height of 1600 m. From the time it started to land, it made a change of 70 m in every minute. How many minutes will it take to descend to a height of 200 m from the ground?An aeroplane was flying at a height of 1600 m. From the time it started to land, it made a change of 70 m in every minute. How many minutes will it take to descend to a height of 200 m from the ground? An aeroplane was flying at a height of 1600 m. From the time it started to land, it made a change of 70 m in every minute. How many minutes will it take to descend to a height of 200 m from the ground?



Sol:
Height at which the aeroplane is flying = 1600 m

Height to travel to come down to 200 m from the ground = 1600 - 200 = 1400 m

Rate of change = 70 m in every minute
