Answer 2

Answer:

Total Distance=100 m

Shyam's speed= 1.66 m/s

Time= $\frac{Distance}{Speed}$

        =$\frac{100}{1.66}$

        = $\frac{10000}{166}$

        =60.24 s

Sujit's speed=$\frac{Distance}{Time}$

                     = $\frac{100-4}{60+12}$

                     =$\frac{96}{60+12}$

                    = $\frac{96}{72}$

                    =$1.33 \ m/s$
