Question 1094065
<br>I will guess that the distance between the two trains is supposed to be 455 miles, and the two speeds are 47 and 44 mph.  Then the combined speed of the two trains is 47+44=91 mph; the number of hours it will take the trains to meet each other is 455/91 = 5.<br>
If you really mean the numbers you show, then simply perform the same calculations using those numbers....
