Question 234569
There is missing data here.

In order to answer this question, I need to know the miles per hour of train b.

Understand?

Please, type the entire question correctly.

==========================================

Thanks for providing the extra piece of information.

The equation is 40(x + 1) = 50x.

Solving the equation, I got x = 4.

The time for train a is x + 1 or 5 more than 8am taking us to 1pm.

The time for train b is x or 4 more than 9am taking us to 1pm.

They meet at 1pm.

=================================================================

The distance for train a is 40mph times 5 = 200 miles.

Of course, train b also travelled 200 miles because 50mph times 4 = 200 miles.
