Question

In a 114-storey building, each floor is 5 m high.
If a lift moves 3 m every second, how long will
it take to move from the 46th to the 106th floor?​

Answer 1

Answer:

Step-by-step explanation:

According to the question,

Number of storeys between 106th and 46th floor = 106 - 46 = 60 floors

Total height of 60 floors = 60 x 5 = 300m

Now, we know that the lift moves 3m every second.

So, time taken to travel 300m = 300/3  

= 100 seconds

= 1 min 40 sec
