B.how did you compute the speed of the two vehicles?

Speed in vehicle A is,
v = x-4/x²-16
v = x-4/(x-4)(x+4)
v = 1/x+4

Speed in vehicle B is,
v = x-4/2/x-4
v = (x-4)(x-4)/2
v = x²-8x+16/2

Car A is 20 miles behind car B, which is traveling in the same direction along the same route as Car A.Car A is traveling at a constant speed of 58 miles per hour and Car Bis traveling at a constant speed of 50miles per hour. How many hours will it take for Car A to overtake and drive 8 miles ahead of Car B?


I tried two formulas to calculate catch up time
1) catch up time when both r moving in same direction=distance between the two/Speed of Car A- Speed of Car B
=> 20/58-50 = 5/2=2.5
to drive 8 miles ahead of Car B by Car A
RT=D
58T=8
T=8/58

Total time= 2.5+8/58 = 2.63 ~=3.0
But answer is different
2) As Car A is 20 miles behind it must have started late than Car B have
so time taken by Car B will be t+x nd
time taken by Car A will be t

As both are moving in the same direction ,both will travel the same distance till catch up time --d

using this information i created two equations and try to solve but
i am not getting correct answer

Relative speed of car A is 58-50=8 miles per hour, to catch up 20 miles and drive 8 miles ahead so to drive 28 miles it'll need 28/8=3.5 hours.

Answer: 3.5

P.S. The way you are doing it should be 20/8+8/8=2.5+1=3.5 hours.

t.s. madali lng solution dyan...

Car A will not overtake car B. because car A will meet an accident. the driver is drunk while driving...
