Answer:
a = 2 5/8
Step-by-step explanation:
14a - (2a + 9) = 3 (12a - 18)
14a - 2a + 9 = 36a - 54
12a + 9 = 36a - 54
12a - 36a = -54 - 9
-24a = -63
a = -63/-24
a = 21/8
a = 2 5/8
To solve this problem you must apply the proccedure shown below:
You must switch the variables, and then, you must solve for
, as following:

Therefore, as you can see, the answer is: 
Multiply by 60, there are 60 seconds in a minute. It would be 1206 meters/minute
