mini bike I x mph
mini bike II x+ 5
..
They are going away from each other.

So add up their speed.

combined speed = x+ 1 x + 5
( 2 x + 5 )
Time = 1 2/ 3 hours
Distance = 100 miles
Distance = speed * time
( 2 x 5 )* 12/31/99 = 100
3.33 x + 8.33 = 100
3.33 x = 100 + -8.33
3.33 x = 91.67
/ 3.33
x= 27.5 mph mini bike I
mini bike II 27.5 + 5 = 32.5 mph
