In the above question , calculate
(i) distance travelled from `O` to `A`.
(ii) distance travelled from `B` to `C`.
(iii) total distance travelled by the body in `16 sec`.

Answer

(i) `12 m` ; (ii) `18 m` ; (iii) `66 m`

Explanation

In Fig., (i) Distance travelled from `O` to `A = "area of" Delta OAE = (1)/(2) (OE) xx EA = (1)/(2) xx 4 xx 6 = 12 m`
(ii) Distance travelled from `B` to `C = "area of" Delta BCD`
`= (1)/(2) DC xx DB = (1)/(2) ( 16 - 10) 6 = 18 m`
(iii) We have already calculated in `Q.3`, the distance travelled by the body from `A` to `B = 36 m`.
Thus , total distance travelled by the body in ` 16` second `= 12 + 18 + 36 = 66 m`
