Answer: The correct option is,
if Ada ran m miles, then Samira ran 2m+3 miles
Explanation:
Given,
Number of miles Samira ran = 3 more miles than twice the number of miles Ada ran
= 2 × Number of miles Ada ran + 3
If m represents the number of miles Ada ran,
Hence,
The number of miles Samira ran = ( 2m + 3 ) miles
