Answer 2

Answer:  Step-by-step explanation:

This is the answer

 f) 1 hour = 60 mins  I min = 60 secs

So 1 HR = 60 mins = (60*60)sec

Therefore 1 hour = 3600 sec

Therefore 7 hours = 7*3600=  25200  1 min = 60 sec, so 52 mins (as per question) = 52*60 = 3120 secs

23 seconds = 23 seconds  Therefore as per question;

7 h 52 min 23 s * 7

=> (25200+3120+23)*7

=> 198401

 h)  similarly  4 hours = ( seconds in one hour) * 4

Seconds in one hour= 3600.       ( 60*60)

Therefore,  seconds in 4 hours = 3600* 4 =  14400 seconds  12 minutes = ( seconds in a minute)  * 12= 60 * 12= 720 seconds

17 s = 17 s  Therefore according to the question,

i.e, 4h 12 min 17 s *9  => ( 14400+720+17)*9

=> 13623

 It was nice  trying a new kind of sum. Hope the answer is correct.
