Question

every floor of a 96 storey building is 5 m high. if a ballon rises 3 m every second, then how much time will it take to rise from 47th floor to 92nd floor?

Answer 1

Answer:

The balloon need 75s to travel the distance.

Step-by-step explanation:

The height of every floor=5m

The balloon has to travel from 47th floor to 92nd floor.

Number of floors to be covered by the balloon

=(92-47)

=45

So, the distance to be covered=(45×5)m

=225m

Now, the speed to rising of the balloon is 3m/s.

So, time required is

Time= distance/ speed

or, time=225/3

or, time=75s

So, the balloon need 75s to rise from 47th floor to the 92nd floor.
