Answer:

2,365,200,000 times

Step-by-step explanation:

Given :

  • Average heartbeat rate = 60 times/minute
  • Avg. human lifespan = 75 years

To Find :

  • Number of heartbeats in lifetime of 75 years

Solving :

  • Let the number we require be n
  • n = average heartbeat rate x 60 x 24 x 365 x 75
  • n = 60 x 60 x 24 x 365 x 75
  • n = 3600 x 24 x 365 x 75
  • n = 86400 x 365 x 75
  • n = 31536000 x 75
  • n = 2,365,200,000 times
