Maxwell leaves his home and walks toward Brad's house at the same time that Brad leaves his home and runs toward Maxwell's house. If the distance between their homes is 50 kilometers, Maxwell's walking speed is 4 km/h, and Brad's running speed is 6 km/h. What is the distance traveled by Maxwell when they meet in the middle?

(A) 16
(B) 18
(C) 20
(D) 24
(E) 30

Distance between Maxwell's and Brad's home = 50 km
Maxwell's speed = 4 km/h
Brad's speed = 6 km/h
Relative speed of approach = 10 km/h
Time = 50/ 10 = 5 hours

Distance traveled by Maxwell when they meet in the middle = 4*5 = 20 km
Answer C

Consider Max starts from Point A and Brad Starts from Point B and move towards each other.
Assume they shall meet at point O after Time 'T'. The question asks us to find OA.

From the question stem we can make out :- Distance OA = 50km - Distance OB
=> 4xT = 50 - 6xT (i.e distance =Speed x Time)
=> 10T = 50
Hence T = 5Hrs

OA = 4 x 5 = 20 Km
Ans (C)

Time taken = Total Distance / Relative Speed
Total Distance = 50 kms
Relative Speed (Opposite side) (As they are moving towards each other speed would be added ) = 6+ 4 = 10 kms/hr

Time taken = 50 / 10 = 5 hrs
Distance traveled by Maxwell= Maxwell speed * time taken = 4 * 5 = 20 kms... Answer - C

Please, consider giving kudos if you find my answer helpful in any way :) :good :thumbup:

Please correct the question
It is not "when they meet in the middle"
it is when "they meet" !!!
Otherwise the answer is obvious 25 km

Hi a2menthiere ,
I believe that the question is correct as it is . In the middle here means a point between their homes . The point does not have to be at the midpoint of the distance between their homes .
Also , since Brad and Maxwell start at the same time and their speed is not the same , they can never meet at the halfway - that is 25 km .

Hope it helps!! :)

Sorry but in my language "middle "means there is the same DISTANCE between two things.
