Continuity Equation: Flow Speed in a Pipe

CLMECH-W4P7YF

Water is flowing through a pipe with a variable diameter. At position 1 in the pipe, the water has a flow speed of $2.2\:m/s$, while at position 2, the flow speed is $5.2\:m/s$.

What is the ratio of the pipe diameter at position 1 to the pipe diameter at position 2: $D_1/D_2$?
