Question

Flora's car is 59/100 of a meter longer than Sally's car. Sally's car is 2/10 of a meter longer than Trevor car. How much longer is Flora's car than Trevor's car?

Answer 1

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

$x=y+\frac{59}{100}$ -----> equation A

$y=z+\frac{2}{10}$ -----> equation B

substitute equation B in equation A

$x=(z+\frac{2}{10})+\frac{59}{100}$

$x=z+\frac{20+59}{100}$

$x=z+\frac{79}{100}$

therefore

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