5 kilometres in 28 minutes. If this runner keeps this same speed for a 50 kilometer race, how long (in hours and minutes) will it take her to complete the race?

Time taken to run 5 kilometers = 28 minutes

Time taken to run one kilometer :-

[tex] = \frac{28}{5} [/tex]

[tex] = 5.6 \: minutes[/tex]

So , it takes 5.6 minutes to run 1 kilometer .

Time taken to run 50 kilometers :-

[tex] = 50 \times 5.6[/tex]

[tex] = 280 \: minutes[/tex]

280 minutes in hours :-

[tex] = \frac{280}{60} [/tex]

[tex] = 4 \: \: hours[/tex]

Therefore , it will take 4 hours for the runner to complete her 50 kilometer race .
