Two trains leave stations 204 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour while the other travels at miles per hour. How long will it take for the two trains to meet?

t = 1.23 hours

Step-by-step explanation:

Given that,

Distance between two stations is 204 miles

One train travels at 90 miles per hour while the other travels at 75 (let) miles per hour.

We need to find how long will it take for the two trains to meet.

As both cars travel toward each other, it means they approach with a speed of 90 mph + 75 mph = 165 mph.

Let t is the time when they meet. So,

It will take 1 hour 23 minutes for the trains to meet.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
