Answer:

The speed of the van traveling south is 92 miles per hour

Step-by-step explanation:

The van traveling north travels at a speed 10 miles per hour faster than the one traveling south.

Let the speed of the one traveling south be x miles per hour

The distance traveled by the van traveling north is:

10 * 2.5 = 25

The distance traveled by the van traveling south is:

2.5x

The distance between the vans is:

25 + 2.5x = 255

2.5x = 255 - 25

2.5x = 230

x = 230/2.5

= 92

The speed is 92 miles per hour
