Answer:
point form: 
equation form: 
Step-by-step explanation:
I think
113.04 will be the answer.
15 seconds= 6.66..
45+15=60
20+6.66=26.66 beats in a minute
I think. This might be wrong but that’s how I would do it
I=3+2i
Z=2-i
i=√-1
i²=-1
E=IZ=(3+2i)(2-i)=6-3i+4i-2i²=6+i-2(-1)=6+i+2=8+i.
Solution: E=8+i
