Answer 1

Answer:

The flora car is $\frac{79}{100}$ meters (79 centimeters) longer than the car of trevor

Step-by-step 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:

$F = S + \frac{59}{100}$ -------- (i)

$S = T + \frac{2}{10}$ -------------(ii)

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

Then substitute (ii) in (i)

$F = T + \frac{2}{10}+ \frac{59}{100}\ \ \ //\frac{2}{10}=\frac{20}{100}\\\\F = T + \frac{20}{100} + \frac{59}{100}\\\\F = \frac{79}{100} + T\\\\F = 0.79 + T$

The flora car is $\frac{79}{100}$ meters (79 centimeters) longer than the car of trevor
