Question

In 10 minutes a heart can beat 700 times at this rate how many minutes will it take it for the heart to beat 140 times

Answer 1

We can figure out how many times a heart beats in one minute (so we can figure out how many minutes it will take for 140 times) by dividing 700 by 10. This gives us 70. Now we know that a heart beats 70 times each minute. Now we know it would take 2 minutes for a heart to beat 140 times because 70×2=140.

Two minutes is the answer.
