The correct answer is A, because you have to calculate the distances to how far and how fast they drove, and then add together their amounts of time they drove, as the question asks for a total of how much they both drove, meaning to add their amounts.

Answer: A

120÷40= 3 hours
100÷50= 2 hours
3+2=5 hours
5 hours is the total number of hours they drove.

So the answer would be 
A. Step 1 Divide: 120÷40 step 2 divide: 100÷50 step 3 add the two quotients.


I hope this helps!!!!!!!
