Maria told, we are told that maria swam 16 kilometers in t hours with the current and eight kilometers in t hours in the same amount of time against the current.
00:16
And we are also told that the rate of the current is one kilometer per hour.
00:20
And we are asked to find the rate of maria.
00:26
So we are asked to calculate v.
00:28
And know that it's also in miles per hour.
00:34
So we will need to change the kilometers per hour into miles per hour later.
00:40
So let's say the maria's speed is v.
00:43
Then with the current, her speed is v plus one, right? because the current speed is one.
00:50
And in t hours with the current, she swam 16 kilometers.
00:55
Against the current, her speed will be v minus one...
