In 10 minutes, a heart can beat 700 times. At this rate, in how many minutes will a heart beat in 140 times?

Mr.sue thank you

10/700 = x/140

Cross multiply and solve for x.

53 because there are alot of 700 so i take and go

To find the number of minutes it will take for a heart to beat 140 times, we first need to figure out how many beats occur per minute.

We are given that in 10 minutes, a heart beats 700 times. So, to find the beats per minute, we can divide the total number of beats (700) by the number of minutes (10).

700 beats รท 10 minutes = 70 beats per minute

Now that we know a heart beats 70 times per minute, we can determine how long it will take for the heart to beat 140 times.

We can set up a proportion using the beats per minute we just found:

70 beats/1 minute = 140 beats/x minutes

To solve for x, we can cross multiply:

70x = 140

Divide both sides of the equation by 70:

x = 140/70 = 2

Therefore, it will take 2 minutes for a heart to beat 140 times at a rate of 70 beats per minute.
