Mason takes his pulse. He counts 48 beats in 2/3 minute. Mason goes on a bike ride and takes his pulse again. Now he counts 81 beats in 3/4 minute. How many beats per minute did Masons heart rate increase

Answer 1

Therefore, beats per minute did increase for 36.

Explanation:

48: 2/3=x:1

48=2/3 × x

x=3/2×48

x=72

81:3/4=x:1

81=x×3/4

x=4/3×81

x=108

Therefore, beats per minute did increase for 36.
