Angelo’s kayak travels 10 km/h in still water. If the rivers current flows at a rate of 3 km/h, how long will it take to travel 38 km downstream? (In hours) and rounded to the nearest tenth
what's the kayak's downstream speed?
time = distance/speed

To find the time it will take to travel 38 km downstream, we need to consider the speed of the kayak in still water and the speed of the river's current.
When traveling downstream, the speed of the kayak is increased by the speed of the river's current. In this case, the kayak's speed in still water is 10 km/h, and the river's current flows at a rate of 3 km/h. So, the kayak's speed downstream would be 10 km/h + 3 km/h = 13 km/h.
Now, we can use the formula:
time = distance / speed
In this case, the distance is 38 km and the speed is 13 km/h. Plugging these values into the formula, we get:
time = 38 km / 13 km/h
Dividing 38 km by 13 km/h gives us approximately 2.92 hours.
Rounding to the nearest tenth, the time it will take to travel 38 km downstream is approximately 2.9 hours.
