Question

Flora’s car is 59/100 meters longer than Sally’s car.Sally’s car is 2/10 of a meter longer then Trevor’s car.how many longer is flora’s car than trevor’s car?

Answer 1

The flora car is
`(79)/(100)` meters (79 centimeters) longer than the car of trevor

Explanation:

We can represent this situation through a system of linear equations.

Let's call F the length of Flora's car

Let's call S the length of Sally's car.

Let's call T the length of the trevor car.

Then we know that:

`F = S + (59)/(100)` -------- (i)

`S = T + (2)/(10)` -------------(ii)

We must find the relation between variable F and variable S.

Then substitute (ii) in (i)

`F = T + (2)/(10)+ (59)/(100)\ \ \ //(2)/(10)=(20)/(100)\\\\F = T + (20)/(100) + (59)/(100)\\\\F = (79)/(100) + T\\\\F = 0.79 + T`

The flora car is
`(79)/(100)` meters (79 centimeters) longer than the car of trevor
