As given,
Step 1: Pick any three-digit counting number
Lets pick the number 643
Step 2: Reverse the digits of the original number.
So, reverse becomes 346
Now, it says that the difference of these two numbers has a tens digit of 9.
Lets, check:
![643-346=297](https://tex.z-dn.net/?f=643-346%3D297)
So, its true that the difference has a tens digit of 9.
Another example:
Lets take 449
So reverse is = 944
Difference = ![944-449=495](https://tex.z-dn.net/?f=944-449%3D495)
Here also the tens digit is 9.
So, the condition applies to all 3 digit numbers.
Answer:
<h3>4.84*10^-4hours</h3>
Step-by-step explanation:
Speed = Distance/Time
Time = Distance/Speed
Given
Distance = 1.2m = 0.012cm
Speed = 24.8cm/hr
Get the time;
Time = 0.012/24.8
Time = 4.84*10^-4hours
Hence it will take the water 4.84*10^-4hours to reach the top of the dock
