subtract 78h 59min 45sec from 80h 16min 37s

Answer 1

Answer:

subtract 78h 59min 45sec from 80h 16min 37s=4612sec

Step-by-step explanation:

we have to subtract 78h 59min 45sec from 80h 16min 37s

so let's convert  78h 59min 45sec into sec's.

1h=60min; 1min=60sec; 1h=3600sec

78h 59min 45sec=(78x3600+59x60+45)sec

78h 59min 45sec=(280800+3540+45)sec

78h 59min 45sec=284385sec

let's convert   80h 16min 37s into sec's

80h 16min 37s=80(3600)+16(60)+37sec

80h 16min 37s=288000+960+37sec

80h 16min 37s=288997sec

subtract 78h 59min 45sec from 80h 16min 37s=>288997sec-284385sec

=>4612sec
