A variety of questions about rates and proportional relationships involving graphs, tables, and equations.

### Problem

The American antelope (pronghorn) and the wildebeest are among the fastest mammals on the planet, particularly at running long distances. The maximum recorded speed for the antelope is 88, point, 5, space, k, m, slash, h, which it can sustain for nearly one kilometer.
On the other hand, the distance, d, in kilometers that the wildebeest can run in t hours is given by the equation d, equals, 80, point, 5, t.
Assuming both animals are running at constant speeds, which animal can run faster?
Please choose from one of the following options.
