So I have a question. Its a really good question. I'm not sure you'll get it though. Okay so my question is if a train leaves a station at 12 o'clock and moves at a constant speed of 90 mph and another train leaves a different station 2000 miles away in the opposite direction at 2 o'clock traveling at 80 mph. When will both trains cross each other?

Step-by-step explanation:

Train 1 will travel for 2 hours before the second train leaves.

The distance at 2 o'clock is reduced by 2*90 = 180 miles and now is:

Let the trains spend x hours before crossing, then we have following equation for the distance:

The trains will cross at:

The time when trains cross each other will be approximately 12:42

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
