Answer 2

Step-by-step explanation:

⭐Question:-

Every floor of a 20 storey house building in 5 meter high.

If the lift moves 2 meter every second. How long will it take to move from 3rd floor to 15th floor?

⭐Answer:-

✯Solution:-

$Height \: of \: 1 \: floor = \: 5m$

$Number \: of \: floor \: from \: 3rd \: to \: 5th \: = \: 12$

$Total \: distance \: = \: 12 \times 15 \: = 60m$

$∴Time \: taken \: to \: cover \: 2m \: = \: 1 \: sec$

$∴Time \: taken \: to \: cover \: 60m \: = \: \frac{60}{2} = 30sec.$

✿Hence, the answer is 30 Sec.
