Solving a problem in physics, section 38, paragraph 6

6. Two boats are moving towards each other. From the first boat moving with υ1 = velocity of 10 m / s, the ultrasonic signal is sent to the frequency ν1 = 50 kHz, which is distributed in the water. After reflection from the second signal received by the first boat to boat speed ν2 = 52 kHz. Considering the speed of propagation of sound vibrations in the water equal to 1.54 km / s, determine the velocity of the second boat.
