Answer 1

A,B CAN FILL 60MIN AND B,C 40 min and c,a 30 min

then a+b+b+c+c+a,=120/9

2(a+b+c)=120/9

a+b+c=60/9

Answer 2

Step-by-step explanation:

A+B=60

A=60-B

B+C=40

C=40-B

C+A=30

40-B+60-B=30

100-30=2B

B=70/2

B=35

A=60-B=60-35=25

C=40-B=40-35=5

A=25 minutes

B=35 minutes

C=5 minutes
