Now I know A1v1=A2v2 and i have been converting to SI units but I am still not getting the right answer. Would it be something like A1v1=A2(v1+v2+v3)?

call Q the flow per second in each pipe.

Q big pipe = 24+18+13 = 55 L/min

Q little pipe = 24 L/min

Vbig pipe pi rBig^2 = 55

Vsmall pipe pi rsmall^2 = 24

so Vsmall = 24/[pi(1.3^2 /4)]

vbig = 55 /[pi(1.9^2/4)]

vbig/vsmall = (55/24)(1.9^2/1.3^2)
