Because both types of reactions, endothermic as well as exothermic, has an equation for calculating its rate and thoses rate equations are very similar and they center around temperature. the higher the temperature the higher the rate.
Temperature is related to the speed at which a molecules moves. more temp equals more speed. more speed means more chances to ram into other molecules. more collisions mean faster reaction speed.
its safe to say that the endothermic/exothermic aspect is unrelated to the "reaction rate" aspect of chemical reactions

an exothermic reaction is a reaction in which heat is evolved.
during this reaction when temp. isincreased,the molecules are in rapid movement and colliding(increased K.E) and therefore the rate of reaction is increased. whereas in an endothermic reaction, heat is absorbed by the molecules and since heat (increased temp.) is a form of energy, it therefore increases the rate of endothermic reaction

The particles hit each other harder and more often, allowing a greater proportion of them to react.
