This paper is concerned with upper bounds for the distances between adjacent zeros of solutions of first-order linear delay differential equations with variable coefficients of the form where τ>0 and p(t)∈C([t∗,∞),R). By introducing a sequence of testing functions, we are able to derive upper bounds that are better than those in the literature.
