Hello..! :)
Response:
Luis runs 16 km in five days.
Explanation:
Luis goes around the athletics track 4 times a day and the track is 800 meters long. How many km does he travel in five days?
[tex] \sf \green \rightarrow{ \textsf{ \blue{800~m}}~ \blue\cdot~{\textsf{ \blue4}}} = \text{ \orange { \sf3~200~m}}[/tex]
We carry out the respective conversion (from meters "m" to kilometers "km", as requested by the problem), knowing that:
[tex] \sf1~km = 1~000~m1 \: \: km=1000m \: \: 3~200 \cancel{m} \ast \binom { \: \: 1~km}{1~000~ \cancel{m}} = 3.2~km3 200 m[/tex]
(In one day Luis travels 3.2 km)
Now, to determine how many meters it travels in five days we must multiply.
[tex] \sf \orange\rightarrow \red{3.2~\ast~5} = {{ \orange{16~km}}}[/tex]
In conclusion we have that Luis travels 16 km in five days.
¿Doubts? On the comments. Greetings :D
Answer:
16 km
Explanation:
If Luis runs 4 laps every day and the track measures 800 meters, then the number of meters Luis runs each day is:
[tex]\implies \sf Total \;meters \;run \;per \;day = 4 \times800 = 3200 \;m[/tex]
To find how many meters Luis runs in 5 days, multiply the number of days by the total meters run per day:
[tex]\implies \sf Total\; meters \;run\; in\; 5\; days = 5 \times 3200 = 16000\; m[/tex]
[tex]\boxed{\sf 1000\; m = 1\; km}[/tex]
To convert meters to kilometers, divide the number of meters by 1000:
[tex]\implies \sf 16000 \div 1000 = 16\; km[/tex]
