: This is Agnew’s most famous contribution to math lore. It challenges students to determine what time it started snowing based on how far a snowplow traveled in two consecutive hours. This classic problem is still cited in contemporary textbooks like those by Dennis G. Zill as a masterclass in building mathematical models from sparse information. ddx[μ(x)y]=μ(x)Q(x)d over d x end-fraction open bracket mu
