Question

Two vans leave a campground at the same time. One is traveling north at a speed that is 10 miles per hour faster than the other, which is traveling south. After 2.5 hours, the vans are 255 miles apart. What is the speed in miles per hour of the van traveling south? F 56 H 66 G 46 J 36

Answer 1

Answer:

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

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
