Final answer:
To make a total length of 40 meters with one length being 10 meters longer than the other, we set the shorter length as x, resulting in x + (x + 10m) = 40 meters. Solving for x, we determine the shorter length is 15 meters and the longer length is 25 meters. To convert measurements, we use appropriate conversion factors, like 1 kilometer equals 1000 meters for length.
Step-by-step explanation:
To answer the question about making 40 meters with one number 10 meters longer, we need to understand how to manipulate lengths to achieve a desired total. If we have two lengths of which one needs to be 10 meters longer than the other to make a combined length of 40 meters, we can set up a simple equation. Let's call the shorter length x. The longer length will then be x + 10 meters. The sum of these two lengths should be 40 meters: x + (x + 10 meters) = 40 meters.
Combining like terms we get 2x + 10 meters = 40 meters. By subtracting 10 meters from both sides, we have 2x = 30 meters. Finally, dividing both sides by 2 to solve for x, we find that x = 15 meters. Therefore, the shorter length is 15 meters and the longer length is 25 meters (since it's 10 meters longer).
Regarding converting units, the standard unit of length in both the SI and original metric systems is the meter (m). A meter is about 39.37 inches or 1.094 yards. When we need to convert between units, for example from kilometers to meters, we use the conversion factor that 1 kilometer equals 1000 meters.
