All options are wrong, it can't be A because cotton burns with smell of burning paper and similarly it can't be D because silk burns with an odour of charred meat.

No the answer is 200 as the car is having a uniform acceleration of 1m/s^2.So, according to the formula s=ut 1/2at^2, the distance covered (s) = 0 1/2at^2=1/2x1x400=200m.

## Ans 5:

Class : Class 8
speed= distance/time20=x/20so,x or distance is 400m
