Train A drove at a 25mph.

Train B drove at 25% more. This translates into \(\frac{5}{4}\)\(*25\)\(=\frac{125}{4}\)

\(Time=\frac{Distance}{Speed}\)

\(100*\frac{4}{125}\)=\(\frac{16}{5}\)

Let A drove at speed = 100 mph then B drove at speed will be 25% more = 125 mph
Distance drove by A= 100*4
Distance drove by B= 125*B
As, distance will be same
100*4=125*B, B= 16/5 hrs

(A) 5/3
(B) 2
(C) 16/5
(D) 18/5
(E) 4


Find V1 = 100/4 = 25

T2 = 100/(25*5/4) = (100 * 4)/(25*5) = (25*4*4)/(25*5) = 16/5

Answer choice C
