"Samira ran 3 miles more that twice the number of miles Ada ran." This means that to get the number of miles that Samira ran, we will multiply the number of miles that Ada ran and then add 3 to the product.
Assume that Ada ran m miles, the following the steps mentioned above, we can calculate the number of miles that Samira ran as follows:
Samira ran: 2m + 3 miles
Comparing this to the choices, we will find that the correct choice is the second one:
If Ada ran m miles, then Samira ran 2m + 3 miles.
