Solution
Number of heartbeats in 1 minute = 72
Hence, the number of heartbeats in 1 hour or 60 minutes
= 60 × 72
= 4320
Number of heartbeats in 1 day or 24 hours
= 4320 × 24
= 103680
4320
× 24
17280
+ 86400
103680
My heart beats 70 times in a minute.
Hence, my heart beats in 1 hour
= 70 × 60
= 4200
My heart beats in 1 day
= 4200 × 24
= 100800
My heart beats in 1 week
= 104800 × 7
= 705600
