Sarah and Michael ran from point A to point B, immediately turned and ran back to point A, without stopping at all. Points A and B are in a straight line. If Sarah ran at a higher average speed than Michael and both of them maintained their same individual speeds during this entire race, then Sarah beat Michael by how many minutes?
(1) Sarah reached point B 10 minutes before Michael.
(2) Distance between point A and point B is 2 miles.
Let's say you and your friend are going to the mall after office.
Now you've reached 10 minutes early cause you were driving a Bimmer.
So, you can figure out that your car is 10 min faster than your friend's car (while travelling from from office to mall).
Then you decided to go back to office immediately without stopping and your friend is still 10 min behind.
Hence, you'll again gain a lead of 10 min cause you've the same (faster) car and you'll have a total lead of 20 minutes over your friend.
That's what statement 1 is telling you. Sufficient to answer the question.
Answer will be choice A
