Question

A multistorey building has 105 storeys, every of it is 4m high.If a balloon rises 3m every second ,how long will it take to rise from 36th floor to the 96th floor.

Answer 1

96-36=60
total distance=60*4=240m
time=240/3=80s

ANSWER=80 SECONDS

Answer 2

Answer:

Total time taken to rise from 36th to 96th floor = 80 seconds

Step-by-step explanation:

Number of storeys in the building = 105

Height of one storey = 4 meter

Now, Number of floors from 36th floor to 96th floor = 96 - 36

                                                                                      = 60

So, Total height of the 60 floors = 60 × 4

                                                    = 240 meters

Now, The balloon rises 3 meter every second

So, Total time taken to rise from 36th to 96th floor = 240/3

                                                                                        = 80 seconds
