**math**

Let x and y be the two speeds, x>y. First part: after 3 hours of driving towards each other, the distance is reduced from 230 to 20, so 3(x+y)=230-20 x+y=70 Speed of one is 10 km less than the other: x-y=10 We have a sum and difference problem where the solution is x=(sum+...

**Physics**

linear velocity=w*radius inner velocity=w*(r) outer velocity=w(r+.340) So the difference in linear velocities at the track is outer-inner=w(r+.340-r)=.340 w Now consider the tires: they have to have the same linear velocity at the pavement. So the difference in tire velocitys ...
