Answer:
{e}, {m}, {w}, {e,m}, {e,w}, {m,w}, {e,m,w}
Step-by-step explanation:
change the unit
50 km per 1 hour
50 km/h = 50,000 m/ 3600 s = 13.8 m/s
the lorry speed is 13.5 m/s or 0.3 m slower than the limit

Answer:
x=27
Step-by-step explanation:
180-2x-40+180-3x+180-x-50+180-4x = 360
360-2x-40-3x+360-x-50-4x= 360
360-10x-90= 0
10x= 270
x= 27
