Answer #1

for

(i) Distance = Speed*Time

= 1*2 = 2 m

(ii) Distance = Speed*Time

= 2*1.5 = 3 m

(iii) Distance = Speed*Time

= 1*4 = 4 m

(iv) Distance = Speed*Time

= 1*3 = 3 m

Therefore the answer for (i) A, (ii) N, (iii) N, (iv) N

Therefore the overall answer which has to be fed in the space provided is ANNN
