Answer:

  • 30 mph
  • 50 mph

Explanation:

They closed the 200 mile distance in 2.5 hours, so the sum of their speeds was ...

(200 mi)/(2.5 h) = 80 mi/h

If s is the speed of the slower one, then ...

s + (s+20) = 80

2s = 60

s = 30

The slower wander's speed was 30 mph; the faster one's was 50 mph.
