Step-by-step explanation:

Since Bridget rows 1 hour 4 kilometers upstream and 30 minutes (half of one hour) kilometers, downstream, then we have to find the average speed of both times. First, let's find how long Bridget would have to row upstream every kilometer.

Step 1:

60 minutes ÷ 4 kilometers = 15 minutes per kilometer (upstream)

30 minutes ÷ 4 kilometers = 7.5 minutes per kilometer (downstream)

Step 2:

Now, we find the average of 15 and 7.5. To do that, we add the values together and divide them by the number of values there are (2).

15 + 7.5 = 22.5

22.5 ÷ 2 = 11.25

Answer: Bridget takes 11.25 minutes to row 1 kilometer in still water.

Answer: Bridget rows at an average of 6 km per hour. The speed of the current is 2 km per hour.

Step-by-step explanation: Given the distance of 4 km and the two times, 1 hr and 1/2 hr, we can figure the speeds to be 4k/h and 8k/h. The average is 6k/h. The difference between her average and the actual speeds recorded is 2k/h against hr going upstream and with her going downstream.

How many solutions can be found for the equation −4x − 11 = 2(x − 3x) + 13?
Allushta [10]
-4x - 11 = 2(x - 3x) + 13
-4x - 11 = 2x - 6x + 13
-4x - 11 = -4x + 13
-4x + 4x = 13 + 11
0 = 24...incorrect......no solutions for this problem
