Traffic laws

Under traffic regulations, car lights can illuminate the road up to a maximum of 30 m. To check the reach of the dipped-beam lights of their car, Peter stopped car at 1.5 m from the wall. The dipped-beam headlights are 60 cm high. At what height on the wall does Peter have to draw a mark to see if his dipped lights are on properly?

Correct result:

x =  57 cm

Solution:

x=60/30 (301.5)=57 cm
