A boat traveled 100 miles downstream and back the trip downstream took five hours the trip back to 10 hours what is the speed of
salantis [7]

Answer:

  • boat: 15 mph
  • current: 5 mph

Step-by-step explanation:

The relation between time, speed, and distance is ...

  speed = distance/time

__

The speed downstream is ...

  downstream speed = (100 mi)/(5 h) = 20 mi/h

The speed upstream is ...

  upstream speed = (100 mi)/(10 h) = 10 mi/h

The boat's speed in still water is the average of these:

  boat speed = ((downstream speed) + (upstream speed))/2 = (20 +10)/2 mi/h

  boat speed = 15 mi/h

__

The speed of the current is the difference between the travel speed and the boat speed:

  current speed = downstream speed - boat speed

  = (20 mi/h) - (15 mi/h)

  current speed = 5 mi/h
