Faizal and Gary ran in a race. When Gary had completed the race, Faizal had only run 5/8 of the distance. Gary's speed was 75 m/min faster than Faizal's speed. Both of them did not change their speeds throughout the race. What was Faizal's speed in m/min?
3 u --> 75 m/min
5 u --> 5/3 x 75 = 125 m/min
It was 125 m/min.
