Question

an aeroplane was flying at the height of 600 from the time it started to land it made a change of 70 in every minute how many minute will it take to descend to a height of 200 m​

Answer 1

Step-by-step explanation:

here,

the height decreases 70 m per minute

therefore,

70 m in 60 seconds

Or

1 m in (60/70) seconds

1 m in (6/7) seconds

And,

To make the aeroplane at a height of 200 m, height changed = (600 - 200) m

= 500 m

SO,

500 m in (6/7 × 500) seconds

500 m in 428.57 seconds (approx)

500 m in 7.14 minutes (approx)

HOPE IT HELPS !!!!!!!!!!!!!!
