Answer:
Thursday he ran 22 miles
Step-by-step explanation:
First we have to calculate how much he ran on Monday to subtract it from the track and know how much it ran on Thursday
36mi * 2/6 = 12mi
now we simply subtract from the total of 36 miles the 12 miles that ran on Monday
36mi - 12mi = 24mi
this means that on Monday it ran 12 miles and on Thursday it ran 24 miles
