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

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

Explanation:

Let

x-----> Fiora's car

y-----> Sally's car

z-----> Trevor's car

we know that

`x=y+(59)/(100)` -----> equation A

`y=z+(2)/(10)` -----> equation B

substitute equation B in equation A

`x=(z+(2)/(10))+(59)/(100)`

`x=z+(20+59)/(100)`

`x=z+(79)/(100)`

therefore

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