Based on observations, the speed of a jogger can be approximated by the relation v= 7.5(1 – 0.04x)0.3, where vand x are expressed in km/h and
kilometers, respectively. Know that x= 0 at t= 0.
Determine the distance the jogger has run when t= 1.3 h.

Tom Cogwagee Longboat, of the Six Nations of the Grand River, is one of Ontario's best known distance runners. In 1907, he set a new Boston Marathon record, beating all of the previous decade's champions by almost 5 minutes! If he ran the 39.2 km course in 2 hours, 24 minutes and 24 seconds, what was his speed? HINT: we'll need our units to be metres per second - what do you need to convert in the question? 0.221 m/s O 0.272 m/s O 4.52 m/s O 17.5 m/s
