Here's the problem I need some help with!(adsbygoogle = window.adsbygoogle || []).push({});

Two wires are parallel, and one is directly above the other. Each has a length of 61.3 m and a mass per unit length of 0.0209 kg/m. However, the tension in wire A is 29.8 x 10^2 N, while the tension in wire B is 3.21 x 10^2 N. Transverse wave pulses are generated simultaneously, one at the left end of wire A and one at the right end of wire B. The pulses travel toward each other. How much time does it take until the pulses pass each other?

I know how to find the velocity of each wave:

v= sqrt (Tension/mass per length)

vA=sqrt (2980/.0209)=377.603 m/s

vB= sqrt (321/.0209)= 123.93 m/s

I just don't know where to go from here. Thanks!
