penerapan masing-masing pada topik “pengukuran waktu”?​

3 cats can catch 3 rats in 3 minutes ==> 1 rat per minute.
It takes 3 cats to catch 1 rat per minute.
100 rats in 100 minutes ==> 1 rat per minute
The same 3 cats can do it, if they don't wear out and take naps.

To determine the number of cats needed to catch 100 rats in 100 minutes, the rate of cats catching rats is established. One cat can catch 33 rats in 100 minutes, so 3 cats are needed to catch 100 rats in the same time frame.
Based on the provided information, we can determine the rate at which cats catch rats and then apply that rate to find out how many cats are needed to catch a certain number of rats in a given amount of time. We know that 3 cats can catch 3 rats in 3 minutes. This establishes a rate of 1 rat per cat per 3 minutes.
To find out how many rats one cat could catch in 100 minutes, we simply scale up the time: (100 minutes / 3 minutes) = 33.33 repeating, which we can round down to 33 since you can't catch a third of a rat. So, one cat can catch 33 rats in 100 minutes.
Now, if one cat catches 33 rats in 100 minutes, we can calculate the number of cats needed to catch 100 rats in 100 minutes by dividing the total number of rats by the number of rats one cat can catch: 100 rats / 33 rats per cat < 3 cats (rounding up since you can't have a fraction of a cat). Therefore, 3 cats are needed to catch 100 rats in 100 minutes

To catch 100 rats in 100 minutes, you need 3 cats, as that's the same rate established initially (3 cats for 3 rats in 3 minutes). Therefore, 3 cats can still catch 1 rat per minute, which meets the requirement. So, 3 cats are required for the task.

Discovery Learning unggul dalam mendorong rasa ingin tahu dan kemandirian siswa, sedangkan RME (Realistic Mathematics Education) lebih kuat dalam mengaitkan konsep matematika dengan konteks nyata yang bermakna bagi anak SD.
