In an 8.00 race, one runner runs at a steady 11.8 and another runs at 14.5 .How far from the finish line is the slower runner when the faster runner finishes the race?

A toy train is pushed forward and released at = 3.5 with a speed of 1.0 . It rolls at a steady speed for 1.2 , then one wheel begins to stick. The train comes to a stop 3.4 from the point at which it was released.What is the train's acceleration after its...

figure out its derivative so it will be chain rule so its 2(x^2+5x+2)^1(2x + 5) << this is the derivative of the inside and when u have this just sub in 5 so its 2(25+25+2)(10+5) = 1560

and the other question is km/h the units i mean so the question is in an 8.00km race, one runner runs at a steady 11.8km/h and another runs at 14.5km/h .How far from the finish line is the slower runner when the faster runner finishes the race?

im sorry bob but i don't get it :( i don't understand what you mean
