Answer 1

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 2

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 .
