Answer:

6.408924056 miles/hour.

Explanation:

First we have to convert 247.54 km to miles. The conversion factor will be 1 km = 0.621371 miles. To do this I set up my stoichiometry.

247.54km | 0.621371miles = 153.8141773 miles

                 |  1 km

Now we have 153.8141773 miles per 1 day. The conversion factor will be 1 day = 24 hours.

153.8141773 miles | 1 day       6.408924056 miles/hour.

1 day                      | 24 hours

(if you need to know what I did with the stoichiometry just ask! I'll be happy to help!)
