Fedor

Fedor stood in the small pool. Above the surface was a part of his body that was twice as long as part of his body underwater. What height does Fedor have, if his body part below the surface is 5 dm long?

Result

x =  15 dm

Solution:

a=5 b=2a=2 5=10 x=a+b=5+10=15 dma=5 \ \\ b=2a=2 \cdot \ 5=10 \ \\ x=a+b=5+10=15 \ \text{dm}



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
