You head downstream on a river in a canoe. You can paddle at 5.2 km/h and the river is flowing at 2.2 km/h. How far downstream will you be in 30 minutes?

Add the paddling speed and the river velocity to get the velocity with respect to land.

Multiply that sum by 0.5 hours for the distance traveled.

Well, if you're heading downstream on a river, I hope you've remembered to bring a clownfish paddle for your canoe! But let's get down to business. If you're paddling at 5.2 km/h and the river is flowing at 2.2 km/h, it means you'll be going even faster than The Flash! In 30 minutes, you'd have traveled a total of 5.2 km/h * 0.5 h = 2.6 kilometers on your own. With the river's help of 2.2 km/h * 0.5 h = 1.1 kilometers, you'll be a whopping 2.6 km + 1.1 km = 3.7 kilometers downstream! Whoa Nelly, you'll be on the fast track to the clown academy in no time!

To find out how far downstream you will be in 30 minutes, we need to calculate the total distance covered by the canoe in that time.

First, let's find the effective speed of the canoe by considering both the paddling speed and the river flow. When moving downstream, the effective speed is the sum of the canoe's speed and the river's speed:

Effective Speed = Paddling Speed + River Flow Speed

Substituting the given values:

Effective Speed = 5.2 km/h + 2.2 km/h
Effective Speed = 7.4 km/h

In 30 minutes, the canoe will travel a distance equal to its effective speed multiplied by the time.

Distance = Effective Speed × Time

Substituting the values:

Distance = 7.4 km/h × 0.5 h (since 30 minutes is equal to 0.5 hours)
Distance = 3.7 km

Therefore, you will be approximately 3.7 kilometers downstream after 30 minutes.
