A person's heart beats 200 times in 3 minutes. How many times will it beat in an hour (remember...60 minutes in an hour) ?
2 answers:
Answer: 4000 beats per hour
Step-by-step explanation:
<u>200 beats </u> X <u> 60 minutes</u>
3 minutes 1 hour
The term 'minutes' cancel out therefore you are left with beats per hour
<u>200 x 60</u> = <u>12000</u> = 4000 beats per hour
3 3
200 times / 3 minutes = x times / 60 minutes
3x = 12000
x = 4000 times in an hour
A person's heart will beat 4000 times in an hour.

The answer is 5 divided by 1/3
Answer:
Approximately : 135
Step-by-step explanation:
60sec x 3 = 180sec
45 x 3 = 135
60 + 90
GCF = 30
(30 * 2) + (30 * 3) = 30(2 + 3) <== the correct way
The mistake Axial made was he did not pick the greatest common factor...he picked 3 instead of 30.
