Let , time taken is x .
So , distance covered b them is equal :

Therefore , time taken by them is 45 minutes .
Hence , this is the required solution .
Hello,
A=(4,2)
B=(2,8)
(AB)≡y-2=(x-4)*(8-2)/(2-4) ==> y=-3x+14
(BC)≡y-8=(x-2)*1/3 ==> y=1/3 x+22/3
4.1x+29
5(m-100)
I understand the third one but please correct me if I'm wrong
