Donya ran a 3k race at a constant speed in 21 minutes 30 seconds. at this speed, how long does it take her to run 1k?

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

                                                                            = 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.
