\begin{gathered} 1560\text{ beats}\colon60\text{ minutes}\; \; \; \; \; \; \; \; x\text{ beats }\colon1\text{ minute} \\ \text{Multiply the outsides, and equate it to the product of the insides} \\ 60* x=1560*1 \\ 60x=1560 \\ (60x)/(60)=(1560)/(60) \\ x=26 \\ \text{Therefore, the rate is 26 beats per minute.} \end{gathered}
