Your writing is rather hard to comprehend, but I'll try to help out to the best of my capabilities.
If a heart can beat 700 times in ten minutes, that means that it beats 70 times in one minute.
Given that information, we can conclude that it would take two minutes for a heart to beat 140 times, since it beats 70 times per minute. Again, the rate would be 70 beats per minute, or 140 beats per 2 minutes, or even 4,200 beats per hour.
