Can anyone plz tell me why this simple equation set cannot be solved by mathematica?

eqn1 = {D[w[t], t] == 5, w[0] == 0}
eqn2 = {w[t] == b[t]*kel[t] - 400}
eqn3 = {D[b[t], t] == 10, b[0] == 0.00001}
soln = NDSolve[{eqn1, eqn3, eqn2}, {kel, w, b}, {t, 0, 10}]

i am having similar problems with a larger piece of code and i think this simple example set illustrates my problem
plz help soon
thanks
pradeep
