Answer:

See explanation

Explanation:

Average heart beat = Number of heart beats/ time

7.0 years = 7.0 * 365 * 24 * 60 = 3679200 minutes

If there are 69 beats in 1 minutes

There are x beats in 3679200 minutes

x = 253865 beats

x = 254000.00 beats ( to 3 sf)

beats in 7.00 years = 254000.000 beats

beats in 7.000 years = 254000.0000 beats
