Question

A building of 50 floors. Every floor of the building is 6 m high. If its elevator moves 3 m per second
then how long will it take to move from second floor to 42nd floor ​

Answer 1

Answer:

80 second

Step-by-step explanation:

From 2nd floor to 42th floor , it moves 40 floors

The distance the lift has to travel will be

No of floor × height of each floor

40×6 = 240m

speed = Distance/ time

3 m/s = 240m/t

t= 240/3

t = 80 second
