A wave equation which gives the displacement along the Y direction is given by the equation y=104sin(60t+2x), where x and y are in metres and t is time in seconds. This represents a wave

On comparing the given equation with y=asin(ω t+kx), it is clear that wave is travelling in negative x-direction.It's amplitude a = 104 m and ω = 60, k = 2. Hence frequency n=ω2π=602π=30πHzk=2πλ=2⇒λ=π m  and  v=ωk=602=30 m/s
