Length of pendulum (r)= 40 inches Angle covered due to swinging of pendulum in 1 sec (θ)=20°
Distance covered by the pendulum in each second(x)=?
Since pendulum moves in a circle so length of arc will be equal to distance covered by the tip of pendulum in 1sec x=rθ
θ is in degree, conver it into radian

Radian measure  =(π180)  Degree measure

Radian measure  =(π180)20

Radian measure = 0.3490

x=rθ

x=400.3490=13.96  inches
