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 :-

So , it takes 5.6 minutes to run 1 kilometer .

Time taken to run 50 kilometers :-

280 minutes in hours :-

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

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
