How long she waits in Wellington

From the question:

She takes the 10 30 from Christchurch

So:

This implies that:

She has to wait until Wellington arrives at 11 15

So:

So, the wait time is:

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
