Derived Measurements Extened Response

Marks heart beats 16 times in 15 seconds. Atthat rate, how many times will it beat in one minuite?

Mark's heart will beat 64 times in a minute(64 BPM). I got this by knowing that 15 multiplyed by 4 is 60 and thats equal to one minute(Because there are 60 seconds in a minute). Then I multiplyed 16 times 4 and thats 64. Thats how I got 64 as the solution.
