Answer:
331.25 sec...make it sure...if I am correct then follow me
Step-by-step explanation:
Given data
The height of a building is:
h= 53 m
The time taken by a person to climb 1 meter is:
t = 5sec
The expression to calculate the time taken by a person to climb 5 meter is,
t=t×5t′=5×5t′=25 sec
The person slips 1m for every 5m he climbs, so in actual he climb 4m in 25 sec
The expression to calculate the time taken by a person to climb 1 meter is,
4m=25sec
1m=25sec4
The expression to calculate the time taken to climb the building is,
T=h×254
T=53×254
T=331.25s
Thus, the total time taken by him to get on the top of the building is
331.25 s
