Best ResponseYou've already chosen the best response.0Logic being: 120 * 30  3,600

Best ResponseYou've already chosen the best response.1@Compassionate If you calculate the value of 120 * 30 when it arises, the final result of the calculation of the value of x does not change.

Best ResponseYou've already chosen the best response.0Oh, I get it. So, we can solve it by multiplying out regularly, just the tutorial I am doing does it weird and shows the processes. That's what confused me. And since we know x  30, we just say 90  30.

Best ResponseYou've already chosen the best response.0Train A has a speed 15 mi/hr greater than train B. If train A travels 150 miles in the same time train B travels 120 miles, what are the speeds of the two trains? Here is my logic. Train A = x + 15. \[\frac{ 150 }{ x +15} = \frac{120}{x}\]

Best ResponseYou've already chosen the best response.0150x = 120x + 1,800 30x = 1,800 x = 60 Recalling x + 15 for A's speed, 60 + 15 = 75
