It means the crew will do two pieces of work each totaling 1500m. In this case the total amount of work would be 3000m. This would not include the warm up and cool down. The 2k would likely refer to the amount of cool down, although you should put a comma between 1500m and 2k, as in 2x1500m, 2k.
6-2kx=5-2x 2x-2kx=-1 x(2-2k)=-1 x=-1/(2-2k)
5k
2k means 2 thousand
1% of 1500m = 1500m * 1/100 = 15m
My understanding is that 2K means 2,000, like 1K means 1,000 and so on. Also .2K means 200 and .1K means 100.
0m
1500m = 150000cm so it is more
if you mean 2x-1*3 then the answer is: 2x-3
If you mean: -2x+8+20 then it can be simplified to 28-2x
12x - 2x = 10
If it is 1500m, then it is 1500m, no matter how long the track is. If you mean how many laps, that would be 3.75 laps on a 400m track, and 7.5 on a 200m track.
If you mean 2x+4(7x-1) then 2x+28x-4=30x-4=2(15x-2) If you mean 2x+4(7x)-1 then 2x+28x-1=30x-1
