Speed and Time

Vedic Maths trick to find Speed and Time

While walking 1/4th if his Normal speed ravi arrives 40 minutes late. What is the m=normal time to cover distance.

Formula of speed :
Speed = Distance/Time

Speed s1 = 1/4 S s2 = S
Time t1 = t + 40 t2 = T


s1 x t1 = s2 x t2

1/4S x (t + 40) = S x t

1x t + 40 = 4x t

40 = 4x t - 1x t

t = 13.333333333333 mintutes
