Question

[Trần Đức Huy]

Peter and Jacob were running. Both of them run with their constant speeds. They started at the same time and the same place. When Jacob reached the finishing line, Peter had only run 5/8 of what Jacob had run. Jacob’s speed is 75m/min (metre per minute) faster than Peter. What was Peter’s speed in m/min?
