at 1:30 in the afternoon an old freight train and a new dart express train pull out of the new garland station going in opposite
nydimaria [60]

Solution: The speed of old freight train is 0.5 miles per minute and the speed of new dart express train is 1.5 miles per minute.

Explanation:

Let the speed of old freight train is x miles per minute and the speed of new dart express train is y miles per minute.

It is given that the speed of the dart express train is three times faster than the freight train. So, it can be written as,

3x=y ....(1)

The trains are moving towards the opposite directions, therefore the distance between them is increased at the speed of (x+y) miles per minute.

Distance=Speed\times Time

The distance between both train in 15 minutes is represented by 15(x+y).

According to the given information the distance between trains is 30 miles in 15 minutes.

15(x+y)=30

x+y=2

Use equation (1) and put y=3x

x+3x=2

4x=2

x=0.5

Put this value in equation (1), to find the value of y.

y=3(0.5)

y=1.5

Therefore, the The speed of old freight train is 0.5 miles per minute and the speed of new dart express train is 1.5 miles per minute.

<span>The distance poles B and D= (1-1/5)=4/5 yard

</span>The distance poles B and E= BD+DE=4/5+7/10=(8+7)/10=15/10=3/2 yard

the answer is 3/2 yard (distance poles B and E)
