Answer:
a) Joel's heart will be 735,840,000 times in 20 years
b) = 11.91 days
=12 days Appropriately
Step-by-step explanation:
Let's recall our nursery rhymes to help us here...
60 seconds = 1 minutes
60 minutes = 1 hour
24 hours = 1 day
7 days = 1 week
4 weeks = 1 month
30 /31 days = 1 month
12 months = 1 year
240 months = 20 years
Let's kick further to the question now:
To know the number of times Joe's heart beats in 20 years,we must know how many minutes are in 20 years, since the question said his heart beats 70 times per minutes.
60 minutes = 1 hour
1440 minutes i.e (60 * 24) = 1 day
525600 minutes = 1 year
Therefore, in 20 years there will be
525600 * 20 minutes
= 10512000 minutes.
a: Joel's heart beat
70 times = 1 minutes
X times = 20 years (10512000 minutes)
Cross Multiply...
70 * 1051200 minutes
= 735,840,000
Joel's heart will be 735,840,000 times in 20 years
b) If Joel's heart beats for 1,200,703 times ,
It means that it beaten for:
1,200,703 / 70 times
= 17152.9 minutes
= 17152.9/ 1440 days
= 11.91
=12 days Appropriately
Answer:
Step-by-step explanation:
Joe's heart beats 70 beats per minute.
a) There are 60 minutes in an hour.
It means that the number of heart beats per hour is
70 × 60 = 4200 times
There are 24 hours in a day. It means that the number of heart beats in a day is
24 × 4200 = 100800 times
Assuming there are 365 days in a year, then the number of times that his heart will beat in a year is
100800 × 365 = 36792000 times
Therefore, the number of times his heart will beat in 20 years is
20 × 36792000 = 735840000 times
b) If Joe's heart beats 1200703 times, the time that would have elapsed is
36792000/1200703 = 30.6 years
