It takes a beat 2 hrs to travel 16 miles upstream againsta current. If the speed of the boat in still water is 12mi/hr.,what is the speed of the current?The speed of the current is ? mph.

Respuesta :

EXPLANATION

Since the speed of the boat is 12 mph, and it takes 2 hours to travel 16 miles, we can affirm that the speed of the current is the difference between the speed of the boat and the given time.

[tex]\text{Total}_{\text{speed}}=\frac{16\text{ miles}}{2\text{ hours}}=8\text{mph}[/tex]

The difference between both velocities is 12mph - 8 mph = 4 mph

In conclusion, the speed of the current is 4mph
