a person was climbing on a building. He slips 1 m for every 5 metre he climbs up. If the building is 53 m high and he takes 5 seconds to climb 1 metre find the total time taken by him to get on the top of the building.

Assuming the slippage is continuous, his climbing rate is 4 meters in 25 seconds.
So, he scrambles up 53 meters in
53/(4/25) = 331.25 seconds. 
answer is 305
