Answer:
I think the answer is 742,000,000
Step-by-step explanation:
The approximate number of heartbeats in the lifetime of a large dog is 742,000,000 times.
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
According to the question
A small dog’s heart beats about during its lifetime = 530,000,000 times
A large dog’s heart beats about 1.4 times this amount.
i.e A large dog’s heart beats about during its lifetime = 530,000,000 *1.4 times
= 742,000,000 times
Hence, the approximate number of heartbeats in the lifetime of a large dog is 742,000,000 times.
