Question:-

An elevator ascends in Burj Khalifa tower, consists of 163 floors and height 829.8 m, at the rate of 10 m/ sec. How long will it take to reach a height of 600 m?

Solution:-

• a) The speed of elevator in Burj Khalifa tower is 10 m/sec.
• b) Heigth { distance } of Burj Khalifa tower is 829.8 m

To find time taken by elevator to reach a height of 600 m . { we use formula }

Formula : -

${ \bf{ \dashrightarrow{ Time = \frac{ Distance }{Speed } }}}$

We know speed of elevator is 10 m/s & covering distance is 600 m.

${ \bf{ \dashrightarrow{ Time = \frac{ 600 }{10 } }}}$

${ \bf{ \dashrightarrow{ Time = 60 \: sec}}}$

Hence elevator take 60 sec to reach

600 m .
