It took sally 3 hours to go 75 miles downstream and it took her 5 hours to travel back upstream to her starting position. what was the speed of her boat in still water and what was the speed in the current of the water

In the durrent the speed was 25mph
in the still water the speed was 15mph

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
