Question

Brent biked 600 meters on Friday. On Saturday he biked 5 kilometers. On Sunday he biked 4 kilometers, 800 meters. How many kilometers did Brent bike over the three days?​

Answer 1

10.4 Kilometers

So let's do the basic, adding. 5 kilometers on Saturday and 4 on part of Sunday. That's 9. So let's save that. Now for the meters. We know that there are 1000 meters in a kilometer. So add up 600 and 800. That gives you 1400 meters total. Now if we divide 1400 by 1000, we get 1.4. So that is how many kilometers he rode on Friday and and the other part of Sunday. SO now we just add everthing up. 9km+1.4km = 10.4, your answer.
