<human>:  Madison and Gigi have to run a total of 2400 meters in gym class. The track is 150 meters around. If they each have run 6 laps, how many more laps do they have to run before they reach 2400 meters?
<bot>: How many laps have they run? ** The have run 12 laps because 6 + 6 = <<6+6=12>>12
How many meters have they run? ** They have run 1,800 meters because 12 x 150 = <<12*150=1800>>1,800
How many more meters do they have to run? ** They have 600 more meters to run because 2,400 - 1,800 = <<2400-1800=600>>600
How many more laps do they have to run? ** The have to run 4 more laps because 600 / 150 = <<600/150=4>>4
