Problem a truck horn emits a sound with a frequency of 238, Ask an Expert

Academics

Problem: A truck horn emits a sound with a frequency of 238 Hz. The truck is moving on a straight road with a constant speed. If a person standing on the side of the road hears the horn at a frequency of 261 Hz, then what is the speed of the truck? Use 340 m/s for the speed of the sound.

(in m/s)

I don't understand how to get the solution. Can you please help me with this above problem? Thanks.
