Question 328125


If they travel in opposite direction, the distances are equal.

FOR JOHN:

rate = x + 20

Time 4 hours

FOR WILLIAM:

rate = x

Time = 4 hours

4(x + 20) + 4x = 250

Atfer doing the math on paper, I found x to be 85/4.

William's rate = 85/4 o 21.25 mph.

John rate = 85/4 + 20 or 165/4 or 41.25 mph.

I hope this helps.
