$$\left(a\right)onclockB:$$$$25\to 125:\frac{125-25}{290-125}\times 600=363\frac{7}{11}s$$$$125\to 200:\frac{200-125}{290-125}\times 600=272\frac{8}{11}s$$$$200\to 290:\frac{290-209}{290-125}\times 600=327\frac{3}{11}s$$$$\left(b\right)onclockC:$$$$92\to 142:363\frac{7}{11}+272\frac{8}{11}=636\frac{4}{11}s$$$$\left(c\right):$$$$\frac{400-312}{512-312}=\frac{x-125}{290-125}$$$$\Rightarrow x=197\frac{3}{5}$$$$i.e.whenAreads400,Breads197\frac{3}{5}.$$$$\left(d\right):$$$$\frac{92-15}{142-92}=\frac{25-x}{200-25}$$$$\Rightarrow x=-244\frac{1}{2}$$$$i.e.whenCreads15,Breads-244\frac{1}{2}.$$
