distance travels in 20 seconds

s = 0*20+a*20²/2

s = 200a -------------(1)

distance travels in first 10 seconds

s1 = 0*10+a*10²/2

s1 = 50a -----------------(2)

distance travels in next 10 seconds

s2 = s-s1

s2 = 200a-50a = 150a ----------------(3)

s2/s1 = 150a/50a = 3

Distance traveled in first 10 seconds

S1 = u t + 1/2 a t² = 0 t + 1/2 a 10²**= 50 a**

total distance traveled in 20 seconds =

S = u t + 1/2 a t² = 0 t + 1/2 a 20² = 200 a

Distance traveled from 10s to 20s =*S2 = 200 a - 50 a = 150 a*

S1 = u t + 1/2 a t² = 0 t + 1/2 a 10²

total distance traveled in 20 seconds =

S = u t + 1/2 a t² = 0 t + 1/2 a 20² = 200 a

Distance traveled from 10s to 20s =
