I think you can use this:$$Speed = Distance/Time$$

you have :

- Distance = 26 miles
- Time = 1 hour = 3600 secs

so plug in the given in the equation and you'll get:

$$Speed = 26/3600$$
$$Speed = 0.00722 miles/\sec$$ I guess, yet I'm not sure

Hmmm, since they have said he moved with cst speed , isn't it supposed to stay the same? Speed = 21miles/sec?

I'm not sure, but hope I'm right ^_^ , please anyone, correct me if I/m wrong.
