Step-by-step explanation:
A biker must circle a 12-mile track twice. His average speed must be 60 mph.
So, the average time required to cover the distance is

Therefore, his average speed in the second round must be
mph to qualify. (Answer)
X in litres is 67% herbicide
y in litres is 46% herbicide
{x+y=42
{0.67x+0.46y=42*0.55

21x=378
x=18 litres
