2 boys are riding their bicycles on same concrete road. one has new tyres on his bicyle while the other has old and used tyres. which one of them is more likely to skid while moving through a road which has lubricating oil spilled over it? why?

Dear student,

The tyres which are old and used are likely to skid.Because the new tyres are made in such way that there is friction between tyre and road.But in old and used tyre the surface might become smooth due to wear and tear and hence the friction between the tyre and road will be reduced with more chance of skidding.

Regards.
