Train A travels at a speed of 8 km/h, Train B travels at 120 km/h. If the two trains travel at a constant speed, they start from the same station, Train A at 8 and Train B at 9, when will they have percorrere the same space? A) At 12
B) At 11
C) At 10
D) At 13/1 PM

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

b and c are the correct answers.
