On the

On the map of Europe made at a scale of 1: 4000000, the distance between Bratislava and Paris is 28 cm. At what time an airplane flying at 800 km/h will fly this journey?

Correct result:

t =  1.4 h

Solution:

M=4000000 x1=28 cm m=28/100  m=0.28 m x2=x1 km=x1/1000  km=0.28/1000  km=0.00028 km v=800 km/h  s=M x2=4000000 0.0003=1120 km  s=vt  t=s/v=1120/800=75=75 h=1.4 h
