Question

If human heart beats one time in 0.8 seconds then how many times it beats in 1 day

Answer 1

1 days = 24 hours = 24 × 60 minutes

= 1440 minutes = 1440 × 60 s =86,400 seconds




simply

1 day = 24 × 60 × 60 = 86,400 seconds



heart beat 1 times in 0.8 sec.



for one day

$= \frac{seconds \: in \: one \: day}{0.8} \\ \\ = \frac{86,400}{0.8} \\ \\ = 108,000 \: \: times$
