Town A lies 210 miles due east of Town B along a road. Car A leaves Town A at 3:00pm and travels east at rate of 48 miles per hour. Car B leaves Town B at 5:00pm on the same day and travels east along an adjacent road at a rate of 65 miles per hour. At what time will the Car B overtake Car A?
(A) 12pm
(B) 11pm
(C) 11am
(D) 10pm
(E) 12am
Can someone help with this question?
B----210 miles----A
speed of A (sA)= 48 mi/h
speed of B (sB)= 65 mi/h

* A leaves at 3 PM, and B leaves at 5 PM, so A has a head start of 2 hours

At what time will the Car B overtake Car A?
In other words we are interested on how long it takes for B to reach A (after 5 PM), B----0----A

* We can already calculate the distance between A and B at 5 PM,
since A has been moving east for 2 hours, B--distance (d)--A at 5 PM,
d = 210(mi) + 48(mi/h) * 2(h) = 306 miles

Now we can calculate the time it takes for B to reach A, that is t = d / (sB - sA)
t = 306 / (65 - 48) = 18 hours

So at what time B reaches A is 5 PM + 18 hours, convert it clock wise, that is at 11 AM

The answer is C

The questions says overtake and at 11 AM they meet, so 12 PM would be more accurate in my opinion. Although I get your explanation as well.

English is hard and isn’t my native language, so I googled "overtake"
(merriam-webster.com) gives
a: to catch up with
b: to catch up with and pass by

I think the Answer is C because the question "At what time will the car B overtake car A?" is not asking us to answer with an approximation.

If the question was "At around what time..." then maybe I would consider 12 PM, but even 11 AM would be more close to that time than 12 PM.

But also I am still new to this GMAT questions, so I am not sure, maybe a senior can help us?

That question tests the concept of relative speed.
