A boat traveled 60 miles downstream and back. The trip Downstream took 3 hours. The trip back took 30 hours. What is the sleep of the boat in still water ? What is the speed of the current ?

Question

apologiabiology · Answer

so we assume that the speed of the current was constant Speed=distance/time Distance=60 trip down=60/3=20mph trip up=60/30=2mph the speed of the current is the avavarage of the diffarence of 2 and 20 so the diffirance is 18 avagage is 9 so 9mph=speed of current 9+x=20 x=11 so the speed of the boat in still water is 11mph the speed of the current is 9mph

apologiabiology · Answer

The speed of the boat in still water is 11 mph, while the speed of the current is 9 mph. This was determined by solving a system of equations based on the distances and times provided for downstream and upstream travel. Both speeds are important for understanding the boat's effective movement in water with a current.
