Answer:
400/4=100km/hr
315/3=105km/hr.
so ,bus is moving at higher speed.
400×1000=400000×100=40000000cm/14400sec
315×1000=315000×100=31500000cm/10800sec.

Answer:
The bus is moving with higher speed.
- Speed of truck is 400/4=100km/h r
- Speed of bus is 315/3=105km/h r
Speed expression in cm/s :
105km/h r
105×1000 ×100/3600
=105000 /36
=2916.66
Therefore,the required speed in cm/s is 2916.66 .
