Long hot dog

In Kostelec above Black Forest, they made a record-long hot dog. When slowly moved it to the square, one of the spectators decided to measure its length: the size of his footprint is 28 cm; he measured 20 feet in travel direction, counted 5 feet against the direction. How long was the hot dog?

Correct answer:

X =  350 cm

Step-by-step explanation:

s=28 cm  y=v2 t  x+y=20 xy=5  x+y=20 xy=5  x=252=12.5 y=152=7.5  X=s x=28 12.5=350 cm
