Every floor of a 20 storey building is 4m high. A lift moves 2m per se...
Solution:
Given:
Height of each floor = 4m
Speed of lift = 2m/s
Starting floor = 4th floor
Ending floor = 14th floor
To find: Time taken by the lift to move from 4th floor to 14th floor
Approach:
We can calculate the distance between the 4th floor and 14th floor using the height of each floor.
Then we can use the formula: time = distance / speed to calculate the time taken by the lift.
Calculation:
Distance between 4th floor and 14th floor = (14 - 4) x 4 = 40m
Speed of lift = 2m/s
Time taken by lift to move from 4th floor to 14th floor = 40 / 2 = 20 seconds
Answer:
It will take 20 seconds for the lift to move from the 4th floor to the 14th floor.
Note: The answer may vary if there are any stops or delays during the lift journey.
