David:
His Distance = 945
His Time = x
His Speed = z
His Time = His Distance divided by His Speed
His Time =
John:
His Distance = 135
His Time = Four less than David
His Speed = Three Times that of David
His Time = His Distance divided by His Speed
His Time =
His Time =

John's Time was 4 hrs less than David. Therefore:
+4 =
I'm sure you can solve this equation. I'll let you finish it off!
