Answer:
Manisha spent 8 minutes and 24 seconds in a week climibing the stairs of her house.
Step-by-step explanation: (totally my work, not copied)
Convert seconds to minutes.
60x8=480
60x9=540
so, 8 minutes
Find the remaining seconds.
504-480=24
Add remaining seconds to minutes
24sec+8min=8min24sec
So hence, your answer is 8 Minutes and 24 Seconds
Manisha spent 8 minutes and 24 seconds in a week climbing the stair of her house.
