If two buses are moving in the opposite directions, their speed having $$35$$ km/hr and $$30$$ km/hr respectively, find their relative speed ?
The correct option is D $$65$$ km/hr
Here the two buses are moving in the opposite directions
Their speeds are $$u=35 $$ km/hr and $$v= 30$$ km/hr
$$\displaystyle \therefore $$ Relative speed $$=(u+v)$$ km/hr
$$=(35+30) =65$$ km/hr
Hence, the buses have their relative speeds as $$65$$ km/hr.
