Tania is riding a train for $43.6$ miles to get to her destination. The train has $14.3$ more miles to travel before arriving at Tania's destination.

Which equation and solution correctly represent how many miles, $m$, the train has already traveled?

A

$m / + / 14.3 / = / 43.6$

$m / = / 29.3$

B

$m / + / 43.6 / = / 14.3$

$m / = / 29.3$

C

$m / + / 14.3 / = / 43.6$

$m / = / 57.9$

D

$43.6 / + / 14.3 / = / m$

$m / = / 57.9$

A)

m + 14.3 = 43.6

m = 29.3

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Miles to travel: 43.6 Miles left to travel: 14.3

To find the amount of miles that the train has already traveled (m), we know that the sum of that value (m) and the miles left to travel (14.3) is equal to the total miles (43.6)

Mathematically speaking:

m + 14.3 = 43.6

Solving:

m = 43.6-14.3 = 29.9

The correct option is A.
