Answer

Explanation:

Step1: Calculate speed of Train A

Speed is distance over time. For Train A, when it travels 100 meters, if it travels 12.5 meters in 1 second, to travel 100 meters, time $t_A=\frac{100}{12.5}=8$ seconds. So speed $v_A=\frac{100}{8} = 12.5$ m/s.

Step2: Calculate speed of Train B

For Train B, it travels 100 meters in 4 seconds. So speed $v_B=\frac{100}{4}=25$ m/s.

Step3: Compare speeds

Since $25>12.5$, Train B is faster.

Answer:

B. Train B
