Question

erik runs a race at an average speed of x m/s

Answer 1

$\huge\bf\underline\red {question}\:$

1)write down an equation in x and show that it simplifies to x square-9x+8=0

2) write down erik time and distance.

$\huge\bf\underline\blue {answer}\:$

Distance = Speed X time

2x^2 -8 = x(3x-9)

2x^2 -8 = 3x^2 - 9x

x^2 - 9x +8 = 0

( x-8) ( x-1) = 0

x = 8 Or 1

x cannot be 1

x = 8

Speed = 8m / s Time 15 seconds distance = 120m..
