Question

7 hr 29min 37sec- 5hr 38min 49sec​

Answer 1

Answer:

7 hr 29min 37sec- 5hr 38min 49sec = 7.493-5.646 = 1.847hours

approximately 1.9 hrs.

Step-by-step explanation:

convert all terms in hrs for our simplicity

1hour = 60min. ! 1/60hr = 1min

1min = 60seconds. !

(1/60)*60 hr= 1second

1/3600 hr = 1 second

7 hr 29min 37sec

29min = 29/60hr. ! 37sec = 37/3600 hr

7 hr 29min 37sec =

7+ (29/60)+(37/3600) = 7.493hr

5hr 38min 49sec

38min = 38/60hr. ! 49 sec =49/3600hr

5hr 38min 49sec =

5+(38/60)+(49/3600) = 5.646hr

7 hr 29min 37sec- 5hr 38min 49sec = 7.493-5.646 = 1.847hours

approximately 1.9 hrs
