A snowplow heads out to plow a 50 mile stretch of highway when there is already an inch of snow on the ground. The snow is falling steadily at a rate of one inch per hour. The speed of the plow is 50/d mph where d is the depth of the snow in inches.
How long does the plow travel this 50 mile stretch of road? (one way)

"Is it still called integration when dt has not gone to zero?"
Yes; see Wikipedia's Numeric Integration article. Graphing calculators have NINT functions that use finite deltas for what amounts to Riemann sums.
