Step 1

The average heart rate of a typical person is 74.0 beats/min. the number of beats in 5.0years can be calculated by using the following data as follows:

since

1 hour=60 min

1 day=24 hour

1year=365.25day

use the above data to calculate the number of beats in 5.0years as follows:

since the number of significant figures in 5.0years is only two so the answer will be up to two significant figures.

Result:

therefore the number of beats in 5.0 years is 1.9×108 beats.

Step 2

the number of beats in 5.00 years can be calculated as follows:

here, the number of significant figures in 5.00 years is three so the answer will...
