Answer:

7 minutes 10 seconds.

Step-by-step explanation:

Donya ran a 3 k race at a constant speed = 21 minutes 30 seconds

1 minutes = 60 seconds

21 minutes 30 seconds = 21 + (30/60) = 21.5 minutes

At this speed it would take her to run 1 k race =\frac{21.5}{3}

                                                                            = 7.17 minutes

7.17 minutes = 7 + (0.17 × 60) = 7 minutes 10 seconds

At this speed it takes her 7 minutes 10 seconds to run 1 k race.

How to simplify please help
Luda [366]

Okay, the image is a little tough to see, but I believe it looks something like this:

(5² -10 / 17 - 3 * 4) -1

The first step [remember PEMDAS] is parentheses

Next comes Exponents:

(25 - 10 / 17 - 3 * 4) -1

Then Multiplication:

(25 - 10 / 17 - 12) - 1

Then Division [which we can't do yet since it isn't fully simplified], so we skip to Addition... nothing again, then subtraction.

(15 / 5) - 1

Then we can divide:

(3) - 1

Then subtract!

2

The answer to your problem is 2.

Hope that helps!
