The equation of a wave travelling on a string is y=10 \sin [\\pi(5 t-\frac{x}{4})], where x, y are in {\cm} and t is in second. The velocity of wave is

Correct Answer is : 20cm∕s, in x-direction

40 {\cm} \/ {\s}, in x-direction

40 {\cm}\/ {\s}, in -x-direction

20 {\cm}\/ {\s}, in x-direction

20 {\cm} \/ {\s}, in -x-direction
