A body travels the distance $A B = l$ with a speed $2 {ms}^{- 1}$ . Thereafter, it travels $B C = l'$ with speed $1.5 {ms}^{- 1}$ and the remaining $C C' = (l - l')$ with $0.5 {ms}^{- 1}$ . Calculate the average speed for this journey assuming that the body takes the same time in travelling distances $B C$ and $C C'$ .

is approaching a flag station whose platform is

500 m

long. The station master is standing at the centre of the platform. The train starts blowing the whistle when the engine is

1 km

away from the near end of the platform and continues blowing the whistle till engine crosses of the platform without stopping. If the speed of the sound is assumed to be

300 {ms}^{- 1}

, then the duration for which station master hears the whistle is?
