Vula is a river guide on the Gariep River. Robert, a member of the group, is injured. Vula paddles Robert to the nearest pick-up point, 12Kilometres away. Vulu paddles back to his group. if the total paddling time for the return trip(there and bavk) is five hours and the river flows at a constant speed of 1 km/h, calculate the average speed that Vula paddles​

10.4 inches

step-by-step explanation:

2x2x2.6

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
