All about speed -maths

Speed is speed . We learnt speed through real life experiments .That is how fast someone or something travels . to learn speed , we have to understand a few concepts .[-------------------------------------------------] In meeting in the middle or running together at the same time and reaching at different times ,what is uniform speed ,the train tunnels .doing real life experiments really makes me understand the concept .the units are how many km/h ,m/min ,cm/sec. just like we did together in the experiment . we run for 1 second only and see the distance ran while catching your breath . it is fun to learn speed and understanding the concept in such a manner.timeline also helps to visualise every thing . -----[ ]----- the tunnel question is to find the distance by the speed and making sure that the train reaches the tail at the very end .
