Let’s add the two speeds together so we can tell how far apart they are, so they move apart at 1,200 mph. At 3 PM, this is how far away they will be from each other. At 4 PM, they will be double that, which is 2,400. They still need to go 300 miles, which is a quarter of how fast they go in an hour, meaning they need to go for another quarter of an hour. That is 15 minutes, making the time 4:15 when they are 2,700 miles apart, which is answer b.
you would take the number of that colored marble which in this case is green so now we have our numerator which is 8 next we are going to add all of the amount of numbers including the green and we get 50 and 50 is our denominator.
