Question

Christopher berg land holds the world record for most distance run on a treadmill in day. He ran 247.54 km. How many miles per hour did Chris have to run to accomplish this?

note: Can you please explain how to do this and not just give the answer?

Answer 1

6.408924056 miles/hour.

Step-by-step 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!)
