Say you go kayaking over a 2 mile stretch of river. The river is flowing at a speed of 1mph. You go 2 miles upstream, and then 2 miles downstream, back to your starting point, for one round trip. What would your average speed be if that round trip took 1 hour? (show all work)

my average speed = 4 miles per hour (4 mph)

Step-by-step explanation:

Extracting the key information from the question:

*** I went kayaking over a 2mile stretch of river.

*** I went 2 miles upstream

*** I also went 2 miles downstream back to origin.

*** I am only required to complete my average speed if the round trip took 1 hour.

  The total distance that was covered in the round trip (my upstream and downstream journeys) is:

 = 2 miles [upstream] + 2 miles [downstream].

 = 4 miles for the round trip.

Again, we were informed that I spent 1 hour going upstream and downstream.

 This means that the round trip time = 1 hour.

Average speed is simply = total distance covered/total time taken

Here, total distance covered = 4 miles.

Total time taken = 1 hour

Average speed = 4 miles/1 hour = 4 miles per hour

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

the first one
