Maria is riding her bicycle. She rides for 2 hours at a speed of 25.6 kilometers per hour. For how many kilometers does she ride
Readme [11.4K]
The answer is <em>51.2 km</em><em />

How we get this answer is pretty simple once we work it out. So, let's go ahead and get our details needed:

-Maria is riding her bike for two hours
-Her speed is 25.6 km/hr

This means that in one hour she will ride a total of 25.6 km. Assuming she goes that same speed the whole way, she will ride another hour and go another 25.6 km. So if she rode for two hours at the same speed, both getting 25.6 km, then if we add those two distances up, we will get how far she rode in those two hours of her biking.

  25.6
<u>+25.6
</u>  51.2

So our answer is 51.2 km

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you any further! :D
