Here are some numbers you round to 12,000: 11,789 12,013 12,432 11,500 11,999 11,679 or, 12,306 and there is plenty more but those are examples let me tell you why: 11,789 If your number is 11,000 over 500 then it rounds to the next number but if it is under 500 it goes to the regular number 11,000 here is another example:
12,013 it is the same with 11,000 but you want it to round to 12,000 so if it is under 500 it goes to 12,000 if it is over 500 then it goes to 13,000
i.e truch weighs 500 lbs so the car weighs 50lbs. lets say thw truck goes 2 mph so thatll be 1000 for the car to reach 1000 you have to divide and youll get 20. so the car has to be ten times as fast as the truck
