He ran with the speed of 220 meter/min
Distance covered by Manpreet is equal to total distance to be covered to complete the race.
Thus, 2.7 + 0.5 + s*(2/3)hr = 12.
2/3 hour is given time in question.
To find the speed in minutes, it will be converted by multiplying with 60.
Hence, 2/3 hour is equal to 40 minutes.
3.2 +s*40 min = 12.
s*40 = 12-3.2.
s*40 = 8.8km or 8800m.
8.8 km is converted into meters to get the answer in meters per minute.
For conversion, 8.8 is multiplied with 1000, thus 8800 meter.
s= 8800/40.
s= 220 meter/min
