Explanation With 5 best steps 1.Data: Speed 1=V₁= 9km/h Distance 1=S₁= 240 m Distance 2 =S₁= 120 m Speed 2=V₂= 45km/h Relative speed(V) = V₂_V₁ Relative speed (V)= 45km/h_9 km/h Relative speed (V)=36km/h Relative speed(V)= 36×1000m/3600Sec Relative speed (V)= 36000m/3600Sec Relative speed(V)= 10 m/sec Covered distance(S)= 240m+120m Covered distance (S)= 360m. 2. Required: Time taken= T=?? 3. Formula: S= V×T For T T = S/V 4. Solution: Putting values in formula. T= 360 m/10 m/Sec T= 36Sec 5. Result: Time taken= T= 36 Sec
