Answer:
A= 75686400
B= 7568640000
C= 75686400000
Step-by-step explanation:
1 day= 1440 min
1 year= 365 days
365 days*1440 min= 525600 min , 1 year= 525600 min
525600 min*2 years= 1051200 min
(in 2 years) 72 beats*1051200 min= 75686400
(in 200 years) 75686400*100= 7568640000
(in 2000 years) 7568640000*10 =75686400000
