Find MN such that LN = 5.7.

666.67 meters

Step-by-step explanation:

If the lion is running 80 km every hour, you divide 80 by 60 to find how many km a minute. Then, divide that by half to find half a minute. Since there are 1,000 meters in a kilometer, you multiply your last answer by 1,000. This gives you 666.6 repeating, or 666.67 rounded to the nearest hundredth.
