A truck left Auckland for its destination, travelling at 80km/hr. Two hours later, a car leaves Auckland, chasing the truck at 120 km/hr. The car catches up to the truck 30km before it reaches its destination. How far is it from Auckland to the truck’s destination?

The truck travelled in 2h=80(2)=160km

The time taken for truck in 30km=30/80=0.37h=20min

The time taken by car to cross =30/120=15min

The truck travelled in 15min=1/4(80)=20km

The trucks destination is 180km from Auckland

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
