Answer:

Flora's car is 79/100 of a meter longer than Trevor's car

Step-by-step explanation:

Let

x-----> Fiora's car

y-----> Sally's car

z-----> Trevor's car

we know that

[tex]x=y+\frac{59}{100}[/tex] -----> equation A

[tex]y=z+\frac{2}{10}[/tex] -----> equation B

substitute equation B in equation A

[tex]x=(z+\frac{2}{10})+\frac{59}{100}[/tex]

[tex]x=z+\frac{20+59}{100}[/tex]

[tex]x=z+\frac{79}{100}[/tex]

therefore

Flora's car is 79/100 of a meter longer than Trevor's car
