Question

Sam rides his bike k kilometers. Annika rides her bike 2 less than 4 times as many kilometers as Sam rides. Explain why Sam must ride his bike more than 1/2 kilometer to school

Answer 1

Anikka's bike = (4*k) - 2 

(4*(1/2)) - 2 = 0  

It's more than half because anything less would cause Annika to ride her bicycle in a negative distance since
