On a 120 km track, a train travels the first 30 km at a uniform speed of 30 km/h. How fast must the train travel the next 90 km so as to average 60 km/h for the entire trip ?

Speed of the train in the first 30 km, v1 = 30 km/h
Speed of the train in the next 90 km, v2 (to be determined)
Average speed = 60 km/h = (v1 + v2)/2

particle moves 3m north,then 4m east,and finally 6m south.calculate the distance travelled and the displacement?

Distsance=(3+4+6)m = 13m
(Displacement) 2 =3 2+4 2 =9+16 = 25 = (5m) 2
So,Displacement= 5m

A car travels at a uniform speed of 40 km/h and next 30 km at a uniform speed of 20 km/h. Find its Average speed.

Average speed = Total distance covered / Total time taken

Time taken to travel the first 40 km = 1 h 
Time taken to travel the next 30 km = 30km /(20 km/h) = 1.5 h
Total distance...
