The problem requires taking the sum of the length of laps in lane 4, 5 and 6 in other to obtain the value of the total distance. Hence, Greg ran a total distance of 135 meters
Since there are no additional information given on the length of the laps in each lane ; we could use hypothetical values to signify the length of the laps :
The value of the total distance covered is calculated thus :
1 Lap in each Lane :
Lane 4 = 40 meters
Lane 5 = 45 meters
Lane 6 = 50 meters
Therefore, the total distance covered = (40 + 45 + 50) = 135 meters.
