Cal Q. Later measured his pulse and found that his heart beat at a rate of 80 beats a minute at rest. At this rate, how many days will it takes his heart to beat 1,000,000 times? (a fraction of a day is permitted)

80 beats/min

= 4800 beats/hr
= 115200 beats/day

so .....
what do you think?

Right

8.68 is the answer ur welcome

To determine how many days it will take Cal's heart to beat 1,000,000 times, we can set up a proportion using his heart rate at rest.

First, we need to find out how many times Cal's heart beats in one day. We know that his heart beats at a rate of 80 beats per minute. Since there are 60 minutes in an hour and 24 hours in a day, we can calculate the number of beats per day as follows:

80 beats/minute * 60 minutes/hour * 24 hours/day = 115,200 beats/day

Now we can set up a proportion to find out how many days it will take for his heart to beat 1,000,000 times:

115,200 beats/day = 1,000,000 beats/x days

To solve for x, we can cross multiply:

115,200x = 1,000,000

x = 1,000,000 / 115,200

x ≈ 8.68 days

Therefore, it will take approximately 8.68 days for Cal's heart to beat 1,000,000 times.
